A completely new demo version of the game, featuring all new maps and showcasing story-oriented gameplay.
We have made a whole new version of the playable demo, and it's available for Windows, Mac OS X and Linux. There are three maps, not found from the previous demo version or the retail game.
The demo can be played solo or with a friend in couch co-op. Both the story campaign and survival mode are available for cooperative play!
