Doom is a first-person shooter with a background setting that mixes science fiction and horror (of the weird menace style), presented in the form of three episodes, each taking place in a separate general location and played separately. The primary objective of each level is simply to locate the exit room that leads to the next area (conveniently labeled with a red EXIT sign), while surviving all hazards along the way. Among the obstacles are monsters, pits of radioactive waste, ceilings that descend to crush the player, and locked doors for which a key or remote switch need to be located. The levels are sometimes labyrinthine (the automap is a crucial aid in navigating them), and feature plenty of hidden rooms that hold powerups as a reward for players who explore thoroughly. A tally screen at the end of each level (except the last of each episode, which describes part of the plot) helps players aiming for additional objectives, such as clearing the levels of monsters or finding secret areas.
