Combat Arms is a "FREE" FPS Multiplayer game by Nexon. Don't let the free part scare you away, because this game actually feels like a really good clone of Counter Strike Source. Combat Arms boasts character customization abilities, modifiable weapons, multiple game modes, in-game clan system and constant content updates.

The current pool of game modes are Elimination (Team Deathmatch), One Man Army (Deathmatch), Capture the Flag, Search and Destroy (Counter-Strike-bomb-planting-mode-clone), Spy Hunt (a complex but interesting game mode) and Fireteam (Mission-like stages against NPCs). Most of the modes are self-explanatory save for Spy Hunt.

Spy Hunt is a mode where players (Mercenaries) seek 5 intel cases; whenever a player picks up an intel, he becomes a Spy; if a Spy is killed, then he drops all his intels. If a Spy acquires all the intels, then he becomes a Super Spy and all hell breaks loose, because it becomes sudden death. The Super Spy must either upload all the intel in a certain computer in the map or kill all the Mercenaries to win the round.

As you play games, you acquire GPs (money) and Experience. With experience you can level up and unlock new rentable weapons. In this game, you "rent" weapons and upgrades with the GPs. That is, you can keep them for one day, a week, or a month. Of course, the longer you want to keep them, the more you have to pay. Also, with increasing levels, you can join level specific servers to fight against equally matches opponents.

The choice of weapons is very extensive: Assault Rifles, Machine Guns, Sub Machine Guns, Shotguns, Sniper Rifles, and Pistols. Each category has several weapons of the type and can be unlocked at specific levels. You can also check out the stats of each weapon like the Rate of Fire, Accuracy, Damage, Recoil and Portability, to determine which weapon best suits your fighting style. You can also carry grenades, smokescreens, gas bombs, flash bangs, mines and many other support gears. Melee weapons are another incentive to play this game: aside from the regular knife, you can also equip a shovel, tomahawk, and so much more.

In game, as you make double kills and multi-kills, then it's posted on everyone's screen, so it's highly satisfying when you achieve this. You also get rewards for headshot and "nut shot". A word of warning, choose a female model in order to avoid the dreaded "nut shot".

The customization allows you to choose your character and put on accessories like shades or hats; you can also put on an armor which reduces your movement speed by 10%. There is the weapons customizability too where you can attach scopes to zoom far away, silencers to reduce noise and spread of fire, and extended magazine clips. You should get this to your weapons asap as they don't cost much GP.

The best part of the game is that it is constantly updated to fix glitches and prevent hackers from ruining the fun for everyone. The gameplay is very similar to Counter Strike and is thus very enjoyable. You can also manage your clans "in-game" and boast your clan emblem. Combat Arms is best played with friends and using a voice-chatting software like Ventrilo or Teamspeak. This game is free and exciting and contains beautiful graphics, and if you enjoy games like Counter Strike or Modern Warfare, then Combat Arms is for you. Check it out and gun the enemies down.

Fans of the Terminator series will be disappointed with this game filled with repetitive action while general gamers will be haunted by nightmares (not the exciting kind). Unless you are a true fanatic of the Terminator universe, the full retail price of $60 is not worth at all. While the movie franchise might be heading in a new direction to satisfy all our Terminator desires, the producers probably didn't put any effort at all in making the video game.

Set two years prior to the movie events, the game follows the character of John Connor (not played by Bale though) in 3^rd person as he embarks on a dangerous mission along with a few other characters. This is one of the few strong points of the game because the story does a nice job developing the character as John Connor rises from a soldier to a leader. The backdrop is set in a post apocalyptic LA which looks gorgeous, but the models aren't as impressive and the blurry cut scenes fail to portray the excitement of the situation.

The other interesting thing in the game is the Cover Mechanic that utilizes the radial movement menu. When you are in a cover a semicircle will pop up; incline the analog stick toward another cover position to select your destination. This is an easy way to move around the battlefield, but the mechanic isn't perfect. Sometimes you get exposed despite a cover position, while other times you get cornered in a trap. An interesting concept, the cover mechanic wasn't appropriately done.

Most of the game you will be moving in a light jog shooting enemies with three basic types of fire - bullets, shells and explosives. And guess what, there are only three types of enemies. Coincidence? I don't think so. As you will soon realize, the flying drones are best taken out by shells, the crab robots by bullets while the T-600s with explosives. You will be following this routing for 5 whole hours before the game ends. Sometimes you might end up in an open battlefield with T-600s spraying fire at you (they can also take you out with one swing of their arm from 2 yards away even if there is a barrier between you two). These situations are easy to get out of as soon as you find a cover, at which point the robots will blissfully shoot away at the cover position waiting for you to come out and obliterate them.

For a change of pace, the developers have included on-rails sequences where you are placed on the back of a vehicle armed with an infinite ammo weapon. This scenario could've been fun, but here again the developers have been lazy: it's very difficult to aim with the car moving sporadically right and left. It would've been infinitely more fun if we could speed our way through the beautiful post-apocalyptic LA by driving it.

Terminator Salvation could've been a great game, with the revival of the Terminator franchise. But the short campaign (only 5 hours that might seem like 50), lack of online playability (only split screen mode), bad dramatization of what could have been an epic story, lack of enemies, lack of collectibles and goals, repetitive gameplay have killed it. It's a shame, because I was looking forward to it.

The Habu is a half-breed gaming mouse from Microsoft (the corporate giant in the computer world) and Razer (the creator of cutting edge gaming tech) heritage, but does it live up to the awesome names of its parents?

My first impression of Microsoft Habu when I saw it online, with specs aside, was that it was one cool mouse. It looks slick with a smooth curvy design and the blue LED lights on the scrolling wheel and the sides are simply stunning to look at. After I got it from Amazon.com, I wasn't disappointed at the looks; it looked even better in reality. The front of the mouse looks more like a Razer mouse, with long primary and secondary buttons (with rubberized coating that makes it easier to handle), but the rear curve looks similar to the Microsoft Intellimouse Explorer. However, it must be noted that the Microsoft Habu is a big heavy mouse and is primarily for palm-grip gamers. If you prefer finger-tip movements, then some other mouse will be more suited for you.

The software that comes with the CD isn't useful at all. When I installed it, the software didn't display the firmware version and kept reverting back to a lower DPI when I restarted my PC. So, I had to resort to downloading the latest Microsoft Habu software from the internet. It worked fine after that. If you buy a Microsoft Habu, then don't install the driver from the CD, but download the latest version from the internet and install that. First you will need to install the software and after your PC reboots, install the firmware, and you will be good to go.

For the nonbelievers who think that higher DPI doesn't matter much, let me tell you that you will feel a significant difference when you kick up the DPI settings. When everything was ready and set up, I realized what a difference the Habu made compared to my old $9 Logitech mouse! Despite its heavy weight, this gaming mouse felt very smooth and comfortable. It has Teflon feet like most other gaming mice of today, so it glides smoothly over the mouse pad (and I have a horrible mousepad! can't wait to experiment on a SteelSeries QcK pad). In the software, you can set your mouse to a DPI of 400, 800, 1600 and 2000; you can even change it on the fly using two buttons just below the scroll wheel!

The Habu also features the Razer's 1000 Hz ultra polling technology. Even though you can use 125 Hz, 500 Hz or 1000 Hz, I highly recommend keeping the settings on 1000 Hz as it makes a significant difference on how well the mouse responds. 1 ms is sufficient for hardcore gamers.

This wonderful gaming mouse also remains "On" all the time, which means there will be no lag after a certain period of inactivity. This is especially useful for MMORPG players and fast paced video gamers.

The mouse has 7 buttons overall and you have 11 functions as options: Click, Menu, Universal Scrolling, Double Click, Advanced Functions, DPI Settings, Windows Button 4, Windows Button 5, Switch Profile, On-the-Fly Sensitivity and Button Off. The Advanced Functions is my favorite because you can use that function to bind any macro keys (both mouse and keyboard) to your mouse buttons, which is really useful and cool. For instance, you can bind Buy Weapon + Nades + Kevlar in a single mouse button using this function. The DPI Settings is useful because you can assign an on-the-fly DPI button. Instead of having to toggle between 400, 800, 1600, and 2000 DPI, you can assign one button on 800 DPI and the other on 2000 DPI to easily switch between sniping mode and regular mode in FPS games. You can assign Advanced Functions on Scroll Up and Down as well.

The Microsoft Habu also has an onboard memory of 32 KB thanks to Razer's "Synapse" cache tech. This will allow you to store mouse configurations in your mouse so that if you take the mouse to a friend's place or anywhere else, the settings will remain saved and you won't have to fiddle with the sensitivities and DPIs again.

Regarding the ergonomics design, the mouse is for right handed people only. And as mentioned before, this mouse is big compared to the others like Copperhead. The two side buttons can be adjusted. The Habu comes with an extra side button set. One of the sets feature the side buttons towards the center, while the other set features a more rearward side buttons. So you can go for any setup you feel comfortable with.

I've tested the Microsoft Habu with Counter Strike Source, Quake Live, Unreal Tournament 3, and World of Warcraft, and it responds great! My gameplay has improved significantly with the increased sensitivity and smoothness. There might be better gaming mouse out there, but for only $32 (on Amazon.com) this is one amazing mouse that delivers sufficient sensitivity for a casual-hardcore gamer like me. Microsoft Habu is an amazing mouse that looks slick and performs smooth, so I highly recommend it to right handed gamers who prefer palm grip movements.

A big debate amongst gamers nowadays is whether or not they're using the best hardware. Some seem to favor the simplicity of Razer, while others like the familiarity of the old Logitech. Well, this argument cannot be settled with one measly review, but the new Sidewinder X8 surely tips the balance somewhat in favor of Microsoft. From first look, you know you're looking at one bad Mamma Jamma. What strikes you right up front is the fact that this is a wireless mouse. YES- A wireless gaming mouse that is claimed to have near zero lag.

What it has:

The mouse features Microsoft's blue track technology. This is apparently the next generation in mouse lasers, where the red laser at the bottom is replaced by a blue one with better performance (actually, upon inspection in the dark, it's a mixture of blue and red, which is quite cool to see). Apart from that, the mouse has a 2.4 GHz wireless connection, with a 500Hz USB reporting. This is all impressive, but wouldn't mean anything if the mouse didn't perform under gaming conditions. With image processing of up to 13000 images per second, it is virtually lag free.

The Sidewinder X8 felt quite well designed, whether due to personal preference or otherwise. It's not so large as to put off players with small hands, nor is it too small. The buttons are quite well placed, although the two buttons on the left under your thumb should've been made stiffer, because it is possible that you will accidentally press them during the heat of the game.

Seven out of the twelve buttons are programmable. As with most modern gaming mice, you can adjust your dpi settings at the touch of a button. The cool thing about the X8 is that it has a ‘on the fly' macro recording button as well, with which you can record macros while you're playing. Heck, there's even an LCD to show your dpi settings!

Another great thing about the mouse is the wire management ‘puck'. It is a round, nifty little piece of equipment which u wrap your wire around. Also, inside the puck are interchangeable Teflon feet, that you can attach to your mouse to vary the amount of glide that you have with the mouse. This is a cool, albeit needless addition.

The Microsoft Sidewinder X8 holds a single rechargeable NiMH AA battery, which goes for 30 hours (or is supposed to) after just 20 minutes of charging. The charging solution is brilliant, because the tip of the wire is magnetic and simply latches on to the mouse to charge. The whole system is quite portable and easy to manage, and this is a great plus point for the mouse.

What it doesn't have:

The most annoying thing about the mouse is the scroll wheel. Its loose, makes a creaky sound, and just feels wrong when you use it. The left and right tilt is also pretty awkward, since the whole movement is really small, and you can never be sure if you're using it right or not.

The mouse is not at all for the left handed gamer. If you're left handed, this mouse will give you nightmares.

The lack of adjustable weights is quite a surprise. Although the adjustable gliders are a nice touch, the weights would have been much better for the serious gamer, who wants just the right feel from their gaming mouse. The mouse also has the usual limitations on what kind of surfaces it can be used on. No breakthroughs were made in this department, since using it on coated glass, or reflective surfaces is a really bad idea.

The design fit my hand perfectly, but has been known to ‘not agree' with some people's personal choices. You should see the size of the mouse in store, and determine for yourself whether you're buying gaming goodness or Carpel Tunnel syndrome.

The retail price of the mouse is 100 USD, which is quite high for a gaming mouse. Maybe some people might think it is worth it because of the wireless freedom, but if you're not very excited about the wireless factor, then you are much better off going for a cheaper, wired gaming mouse.

The conclusion:

The sidewinder x8 is a great leap forward from Microsoft ‘s previous sidewinder gaming mouse. Although it does boast the ‘revolutionary' new blue track technology, it is not without its flaws. Sure they have made a great gaming mouse, but it is not without the small flaws. The hundred dollar price tag might appeal to the gamer who wants wireless freedom and ultra smooth sniping action under one package, but it certainly is not for the average computer user. If, however, you're a fan of the sidewinder series, and are looking to upgrade, then this mouse is definitely worth it.

So you know how to time the items and weapons in quake live, and you have a good idea of which weapon to use in what situations, but do you know how to combine these skills and add a sense of map control to your arsenal to dominate your opponent? Godlike aim aided with an inhuman sense of timing won't help you win battles unless you can control the map like a pro.

As mentioned earlier, your first priority should be to maintain control of the major items and the weapons. By major items, I mean the Red Armor and the Mega Health, and by major weapons I mean the Rail Gun and perhaps the Rocket Launcher. Never get greedy enough to rush in for 1-2 frags if that means you have to give up one of the items. If your opponent is low on health, let him run; try to finish him off with Lightning Gun or the Machine Gun, or perhaps the Rail Gun. If you can't, then let him rush to his health. You should get back to timing your items, picking them up, and then going in for the kill.

But to do this, you need to know the maps of quake live by heart. You need to know each route in the map just like you know the back of your hand. You need to develop a sense of length and height, and the amount of time it takes to go from one position of the map to the other. This might seem intimidating, but there is no complex calculation to do here; this comes with practice and becomes second nature.

If you have the cognitive mapping of an arena thoroughly in your mind, this will help you ambush enemies and track them down. For instance, if they are low on health, they have most likely gone to pick up some yellow or orange health spheres. So your idea should be to take a different route and make a prediction shot at the yellow or orange health spheres. Majority of the time, your prediction will hit a bull's eye. Of course, this also requires you to master strafe jumping (more on this later) so that you can go from point A to point B fast.

Another great advantage of knowing a map well is that you can respawn kill your opponents. All the maps have certain spawn points, and with time you will figure out where enemies will spawn next after getting killed. This type of prediction is very important as this will get you more than half of the kills in a round. If you know where the enemy might be spawning next, your job will be to strafe jump your way towards that place and frag your opponent before he can acquire weapons or armor. Lots of skilled players abuse their inhuman knowledge of the map to make you their play toy. So practice a lot and learn the different spawn points.

If you have a sense of time, then your predictions will get even better. If you know an opponent is going around a map, then you will be able to go ahead of him to ambush him with some prediction shots. You should also utilize rocket jumps to cut ahead of your enemies and surprise them. Rocket jumping also helps against enemies who might be chipping at you from a platform with a Rail Gun. After he takes a shot, rocket jump up and fire away before he can switch his weapon.

Taking long distance shots at the enemy with the rail gun is one of the most useful ways of making sure that your enemy is always on the run looking for health. This is also a great way to keep them off the armors and mega health or the Rail Gun. So abuse the Rail Gun and the settings of most map to the fullest and make your enemy's life a living hell.

If sometimes you have to confront your enemy Rail vs Rail, then do so if you are on the RA side of the map. You know that after getting a shot or two you can always run back and pick up the RA. Likewise, you know that your enemy will be heading towards the YA or some health spheres. So as soon as you pick up the RA, head towards somewhere near the YA and make a few prediction shots. But of course, a clever opponent will be expecting the same from you, so turn corners carefully to avoid prediction shots from your opponents. Listen for rocket sounds so that you can avoid them.

When engaging in combat, choose your position. Most often a higher ground will give you a greater advantage. At other times, utilize pillars and walls to hide behind while your Rail Gun is reloading. Whenever you can, try to attain the higher ground so that you can rain down rockets on your opponents or take Rail shots at him with more precision.

Nothing beats practice. So practice as much as you can and the map will become like an open book to you. Only when you truly know every route of a map, including rocket jumping and strafe jumping routes, will you be able to call yourself a truly skilled quake live player.

A key skill in Quake Live is determining what weapon to use in which situation. If you think you have a sick aim and prefer using the rail gun or the rocket launcher all the time, then you will see that against better opponents you will start losing. Quake Live isn't all about aim; you need to choose your weapon wisely in combat and also make sure that your opponent is cut off from them.

As you might already know by experience, the Rocket Launcher is your friend in close combat while the Rail Gun is your best bet in a long range fight. For mid range confrontations, you can either go for the rocket launcher or the lightning gun. The Lightning Gun has been nerfed in Quake Live, but it's still a potent weapon to take out an enemy quickly. The grenade launcher is a good spamming weapon to keep enemies away or to ambush enemies who may be coming through tight corridors or doors. When you know that the enemy is low in health (when you hear them screaming), finish them off with the Shotgun if in close range, the Machine Gun if enemy is retreating and far away, or the Lightning Gun if the enemy is in mid range. Although I myself don't prefer using the Plasma Gun, in the hands of high skilled players, it is a deadly weapon. Plasma Gun is good for taking out enemies in close quarters or spamming doors or corridors, and not to mention Plasma Climbing!

According to my experience, Rocket Launcher is the most versatile weapon in Quake Live. It deals insane amount of damage with direct shots, and the splash damage makes it all the more easier to blow enemies into giblets. If you hit an enemy near the ground with a rocket, they will bounce off which makes it significantly easier to target and hit them with another rocket as they come down. If you are skilled enough, you can finish them off even before they can land by air rocketing them. The rate of fire of a rocket launcher is fast and this is what makes it the weapon of choice for most gamers. As if these weren't enough, you can even Rocket Jump (more on these later) to unreachable heights and cut off your enemies' escape or surprise them. The Rocket Launcher is also an excellent weapon for spamming at items as they respawn or spamming doors and corridors if you can predict that they are coming through.

The Rail Gun is the other most used weapon in Quake Live. Although its damage has been nerfed from 100 to 80 per shot, it is still a lethal hitscan weapon. If you have the rail and your opponent doesn't, you will usually be able to fend him off from important items by chipping at him from a distance. If you can land a shot or two, this often makes enemies run away for health or armor shards, leaving you open to take the MH or RA. Skilled players usually make sure that the opponent doesn't get the Rail. Some people even camp the Rail Gun obsessively, but I wouldn't recommend that, because sticking to one weapon only is a sign of weakness, and skilled players will definitely capitalize this mistake. The main drawback of the Rail Gun is its reloading time and the humming sound it makes that can alert players of your location. Other than that, it's a great weapon for harassing your enemies and taking them out from a distance.

The Lightning Gun is another fatal weapon in the hands of a skilled player. You can either aim by moving your mouse (more useful if opponent is in the air) or by moving using the strafe keys (more useful while enemies are on the ground and strafing). You can combine both methods to truly make yourself deadly. However, if you are too close to the opponent, be careful if they have a rocket and are very good at using it. But in most cases, you will be able to take them out if they don't have armor. The Lightning Gun is especially useful for taking out enemies as they are retreating for health. Some people say that the Lightning Gun is unbalanced, but it really depends on who is using it. Most people have a tough time keeping their aim straight. So master this, and you will be a force to be reckoned with.

As stated earlier, the grenade launcher can be used in very interesting ways. They are most useful if you are good at predicting your opponents. See some demos of how the skilled players spam certain points on the map with grenades and keep away enemies from important items like the RA or MH.

The Shotgun is underrated by most people. You can deal massive damage in close encounters and take out enemies with a shot or two. It's a good weapon for ambushing if you don't have the rocket launcher. It's also excellent for finishing off enemies when you know that their health is low. The art of using the shotgun is moving your mouse fast enough and precisely enough to predict which way your opponent is moving and fire away. Shotguns can turn the tide of a duel if used wisely.

The Plasma Gun is most useful for taking out enemies in close quarters or spamming at item locations. Sometimes you will see enemies waiting for an item to respawn (usually RA, YA or MH). You can then fire away at them and hope to take out enough health that they will retreat. The trick is to spray fire in an arc and shoot ahead of where the enemy is moving. This makes it harder for enemies to dodge them.

The Machine Gun is weak, but it is a hitscan weapon, which makes it lethal when taking out enemies from a distance if their health is low and they are retreating.

Of course, the rules of using these weapons are not set in stone, but you now have a basic idea of what weapon to use in which situation. Practice using the different weapons and try to control the Rail Gun and Rocket Launcher on the map, and you will be one step closer to becoming an unstoppable player.

Every fan of first person shooters knows what a Duel is - two players are thrown into the arena to fight it out for supremacy, like gladiators in Ancient Rome. The player who has the highest points after a set amount of time wins. There are no teammates here to back you up. You are on your own in this game mode, and victory determines the better Quake Live player.

In Quake Live, you can either play online with a matched opponent with similar skills (they don't work all the time, trust me) or practice against bots. In the online duel servers the time limit is set to 10 minutes and the frag limit is set to 0. If you enter a server where there are more than two players, then you are queued in a waiting line. After each duel, the loser is rotated to the bottom of the queue while the next person in line enters the arena to fight the winner. This process continues.

To get points in a duel, you have to frag your opponents. For each frag you make, you get 1 point, but for each suicide, lava or void death you lost 1 point.

Throughout a duel, your strategy should be to control the map by timing the Red Armor and Mega Health and picking up other essential items and weapons.

The Red Armor (RA) will give you extra 100 armor.
The Yellow Armor (YA) will give you extra 50 armor.
The Green Shards will give you extra 5 armor.

The Mega Health (MH) will give you 100 health, and this can take your health over 100.
The Orange Health Spheres will give you 50 health.
The Yellow Health Spheres will give you 25 health.
The Green Health Spheres will give you 5 health, and this can take your health over 100.

When a duel starts, all the items the map will spawn, so you should get the Red Armor or the Mega Health as soon as you can, whichever is closer to you, and then start timing them. The RA and YA respawn every 25 seconds while the MH respawns every 35 seconds (except in qztourney4 [vertical vengeance] and qztourney6 [almost lost]).

In Quake Live the timer counts down to 0, so to quickly calculate use the subtraction addition method. If you pick up RA/YA at 54 seconds, quickly subtract 30 seconds and then add 5 seconds to find the time of the next respawn. So, 54-30 = 24+5 = 29s. For MH, if you pick it up at 54 seconds, subtract 30 seconds and then a further 5 seconds. So, 54-30 = 24-5 = 19s. Of course, this is a hassle for beginners and could be very troublesome during a duel, but with enough practice, this becomes second nature.

If you miss the timing, then listen well for a sound cue. Every weapon and item has a different sound when picked up. So when you hear the sound of the RA being picked up, quickly calculate the time for the next respawn.

Other sound cues will drastically change your skill level if you employ them right. Listen for enemy movements to learn their location. They make noise when jumping and falling, and if they use a jump pad, that has a particular sound effect too. When they are low on health, they will start screaming when taking damage, so it might be the right time to switch to a more appropriate weapon to finish him off.

In the next section, we will talk about weapon choice.
