To me the game is all about the Multiplayer(Mostly online)
DarkOps = Eradication, Onslaught, Infection, Sabotage.
Thats all there names but i dont feel like explaining about them.
Just in DeathMatch you like respawn after killed in DarkOps most games you dont respawn till next round but some you do. Vehicles- HoverCraft car thing, and Jetpack.
Guns- A nice variety from pistols to snipers and all in between.
Levels- Theres not alot but you could download 4 New ones of Xbox Live Market which are good.
Community- (people playing online) are mostly cool and easy to get along with.
Games up to play- A good amount in my opinion.
Graphics are nice to.
Theres alot of little thing you could do in a game like cover behind things and such
So that should be a good example of things.If you want a good Online Multiplayer this is your game.
