It wouldn't make sense to go without one of the biggest sellers of the year in this roundup; COD4 has risen up the ranks to become a huge contender in the FPS arena.

Multiplayer in Call of Duty is a bit of a stretch for those used to playing in Source games or many other shooters, from death to respawn the action is very quick because the battle area is a lot more intense with a lot of action always going on as people fight to hold points or take them down. Add in the element of the support chopper and the air raid and more and this battle really heats up for people. The G9 in this case returned to full glory, 3200DPI with the polling still at 1000Hz. Sleeved up still on the textured grip I set off into battle.

The speed of the matches in COD4 are really fast and the game works to keep players in a sense that they're experiencing the action firsthand, as a result when someone throws a grenade or a stream of fire comes through the player is quick to duck, turn and jump out of harms way when it comes along. The G9 in this case is really amazing, aiming is quick and spot on when it comes to picking off people, instead of worrying about lining up the sight the mouse manages to flow along nicely with the amount of data it's picking up in such a short movement, in close combat this is really nice when it's essentially spray and pray and the person who kept their mouse focus the steadiest will probably win.

Vacant and Shipment were the focus of the test, both taking things through a series of indoor and outdoor experiences, pushing the other side and also taking a beating at times when the tides shifted in the power struggle for teams to hold the best ground, for me the G9 barely felt to be a burden in any form as it pulled left and right without problem. The buttons were smooth and action felt seamless, the speed of the mouse was enough to save me from narrow misses quite a few times in game as well. I did notice that in close quarters though, the mouse cut around quite fast, for those camping on the floor they had an extra moment to react as whipping around leaves a bit of spray and pray going on before the bullets find a center again, the Deathadder was actually close on this for me, even with the settings high but not peaked it seemed to flow steadily for game play in quick targeting and rushing, the G3 and G5 were fast but I didn't feel the same overall pacing for some reason.
