We are having the same problem in Dante's Theater in 2 player mode. We move rather quickly until we get on the stage. We hack the computer and then we die within seconds. We have tried different positions on the stage, using mahcine guns, smoke bombs, but can't seem to kill the enemies before "misson failed". I do not claim to be a gamer but am addicted to this game and want to pass this level. Please help us.
