Right, a mate bought this yesterday, and we would like to go through it together in co-op mode. However... you can only play maps in co-op mode that have been completed in single player mode and we would much prefer to go through the game together, with neither person knowing what to expect.
I've had a look round t'internet but I cannot find any cheats. Anyone know if there is a level unlock/select cheat for it?
Cheers!
