Call of Duty World at War is based on the previous game, Call of Duty 4.  The only difference is that single player is much more brutal and fast paced.  Now, you would have to watch out for bayonets coming at you and explosions around you.  In this game, you can dismember enemies depending on what kinds of guns you use, it is not about winning the game anymore, it is about surviving the war only will then you experience what WW2 soldiers endured back in their days.  Multiplayer is just as fun to play as Call of Duty 4.  Instead, you can drive tanks, call dogs, or an artillary strike.  I recommend...
