Overview

In Doom, the archetypical first person shooter, you navigate various levels. Along the way to the exit, you will encounter monsters. To assist you in defeating them, you will find weapons and powerups. You may also need to find switches and/or keys to finish a level.

At the completion of each level, you are rated as to kills (the percentage of the monsters on the level that you killed), items (the percentage of certain powerups that you picked up), and secret (the percentage of certain hidden areas you visited). Your completion time (in minutes and seconds) is shown, along with the author-determined par time.

Your kills may exceed 100% if the level contains an Arch-Vile monster. The Arch-Vile can resurrect dead monsters, and you get credit for each time you kill them.

If the game shows secret 0% it means either that you found none of the secret areas, or that the level contains no secret areas at all. Nearly all the levels supplied by id Software contain secret areas, but it is more common to find user-created levels that do not.

In deathmatch mode, you use your weapons against other players.
