CoD World at War is currently available at an attractive price, perfect for a two player game session!
Is zombie mode available to coop game play, like it is for console games?
Furthermore, is it possible to play the zombie maps in multi-player mode right after purchasing the game, without having to complete the single player campaign first?
To clarify the second question - Some forum comments suggest completing single player gameplay is required to unlock zombie mode. Is this the case? The zombie mode is probably the most entertaining multiplayer mode, hence I'm keen to get started straight away.
