3.team fortress
Team Fortress 2 doesn't require you to search endlessly for a good server or organize two dozen of your friends in order to play the game the way it was intended. Valve designed everything about Team Fortress 2—the player classes, weapons, level design, and the visual style—in a way that rewards players for working together. Like most recent Valve games, Team Fortress 2 also benefits from frequent gameplay tweaks and additional content, all for free. Unlike much of the competition, Team Fortress 2 doesn’t take itself too seriously—it's a lot funnier than watching brooding space marines trying to blow each other's head off.
4.red faction
Sometimes, we play games to distract ourselves or see a new world or experience an interesting story, but sometimes, it just comes down to that primal desire to blow stuff up. In the category of games that aim to satisfy your destructive urges, Red Faction: Guerrilla has few equals. The secret to Red Faction: Guerrilla’s immensely satisfying spectacle of destruction is the Geo-Mod 2.0 engine, which allows players to dynamically destroy all of the game’s structures. A warehouse full of armed goons standing between you and the only door out? Just plant an explosive charge and make you own exit—or better yet, plant 20 charges and collapse the whole building on your way out
5.call of duty:black ops
We could've put Call of Duty: Modern Warfare 2 here as a budget buy, but when it comes to Call of Duty, you go loud or go home. Black Ops, the latest in the series, has both a strong campaign mode that takes you through some interesting bits of history and a deep multiplayer experience that’s already begun to get new content via map packs and updates. Also, it's No. 1 on the list of most-played multiplayer game on consoles
6.dead space
It's tricky finding a good shooter for the Wii, but if you're going to take a chance on one, make sure it's Extraction. Sure, it falls more in the survival-horror niche, and the shooting is an arcade light-gun experience as opposed to a first-person shooter, but the formula works well on the Wii, and its storytelling is solid. Plus, it's a prequel—so no spoilers for Dead Space or Dead Space 2.
7.bioshock2
BioShock 2 bulked up the shooting elements in the original BioShock to the point where players may dual-wield both the plasmid attacks (read: magic) and various guns. Additionally, you may combine various plasmids and mix up which types of ammo the guns use for a more strategic approach to shootouts with enemies—and then hack turrets and sentries for even more shootery shooting.
8.bad company2
Bad Company 2 is the first major Battlefield release for the PC since BF 2142. It features destructible environments that really take the action up a notch, and like earlier games in the series, it does a great job of catering to different play styles with the class system. Objective-based Rush mode and Hardcore mode are both nice additions. It encourages teamwork more than most shooters, and it stays pretty close to the proven Battlefield formula. Although I miss the 64-player matches and mods of the PC exclusive Battlefield titles, Bad Company 2 is an easy game to recommend
9.call of duty:moder wa fare
Renowned for intense infantry combat, Call of Duty 4 brought the series into a modern warfare setting and quickly became the most popular online shooter of 2007. Multiplayer features received special attention in this release, which has a deep and very addictive persistent stats system that rewards players with upgraded skills and items as they gain experience. Call of Duty 4 also offers a robust variety of multiplayer modes and some of the best graphics in its class.
10.call of duty: world at war
Following in the footsteps of the highly successful Call of Duty 4, this addition takes the series back to its roots in World War II. Call of Duty: World at War has plenty of explosive, flamethowing action, and the deep multiplayer experience system from Modern Warfare makes a return. World at War is the first Call of Duty game to offer solid co-op play, allowing up to 4 players to tackle the campaign online. You can also unlock zombie mode for some old-fashioned hilarity, but the game still hasn't managed to get as much traction as its predecessor
