Yes, in multiplayer, you can cooperate (each controls one paddle), or play against (one player controls both PONG paddles to navigate Pac-Man, the other controls the ghosts to try to eliminate Pac-Man). But in addition to Cooperative mode and Versus mode, there is the very difficult Cooperative Versus mode. In this mode, the game randomly switches between Cooperative mode and Versus mode, and also randomly assigns roles to the players. So you might start the game playing with your teammate trying to get Pac-Man to eat everything in the maze, then suddenly the game switches to Versus and you get control of the ghosts and try to beat the other player by eating Pac-Man. But he manages to eat all the ghosts instead, and the game switches mode again. Now you're back to working together, but you decide to take revenge and run the paddle to get Pac-Man killed. And so on. Needless to say, very few get past Level 1 in Cooperative Versus mode.
