Not for the single player, Multi-player fun often depends on your teamates
I won't go into details about the play, there are a million places you can go for that, but I will say there seem to be differences between the PC version and the Xbox version. The A.I. seems about the same, but the Director seems a little bit more varied and random in the PC version. In the Xbox version, you kind of knew that the Tank or the Witch would show up at a certain part. One thing that surprised me, my accuracy doesn't seem to go up with a mouse. I can get more head shots if I tried, but mostly your just trying to keep the zombies off of you anyway.
This game is great, but for the anti-social, there is nothing here for them.
