I guess the manual considers the Combat Simulator (the multiplayer mode) only 35% of the game even though, for me, it was the main draw, and the place where I spent the majority of my time with it. Anything related to the single player mode is not available, which includes co-op and counter-op. A few small features are disabled in the Combat Simulator though, which includes the character select, music select, naming teams, three or four players, and the two-player is done with tiny boxes similar in size to the four-player mode.
