"Co-op is as solid as ever, and still the only realy way to play, splitscreen or online, you and your mate can work together outwitting the enemy and saving each others keisters to great effect. Online play returns and is solid and addictive, with a whole host of options to allow you to tailor the team based carnage as you desire.
Gears of War 2 is a prime example of 'if it ain' broke, tweakk it. No major changes but loads of small improvements add to the experience. And a lengthy single player as well as multiplayer as solid as they come. If you have to kill things, you should bloody well kill a few locust. Prefereably by chopping them in half."
