A fun multiplayer classic.
Wizard of Wor is an action game. The screen is set up in Pac-man like maze levels, with the player controlling a "Worrior". The levels are infested with monsters, and you have to find them and kill them before they kill you.
Where this game really shines is the multiplayer. Two players can play simultaneously, each controlling their own Worrior. Along with killing the monsters on the screen, you can also kill the other Worrior. Or, if you'd rather go the cooperative route, both players can work together through the several levels of the game.
