How does the multi-player gameplay work?
=============================================== In DOOM, players are able to see each other, and watch each other jerk in pain as they are hit during the game. Players are able to watch others get hurt, die, and move throughout the labyrinth. DOOM allows players to play together, working as a team. In this cooperative mode, players can see each other on an “automap” and switch to each other’s view. DOOM also allows players to play against each other, in DeathMatch mode.
