Computer area map



The computer area map (or just computer map according to the manuals) is a powerup that appears as a gray box with a screen, similar to a computer monitor, upon which is displayed a series of green blueprints. Picking one up will cause unexplored lines in the current level to be shown on the automap in gray. Not all lines will appear, as the level designer can tag sectors to be invisible to the computer area map; this can include certain secrets and most out-of-bounds areas (such as closets that monsters are stored for teleporting).

The computer area map's power can also be obtained with the cheat code. (The cheat code is similar but reveals even more information, although it does not distinguish between seen and unseen areas.)

Computer maps last until the level ends or the player is killed.

This item is included in the items percentage displayed at the end of each level. However, after one map item is obtained in a single player game, any additional map items on the same level cannot be picked up. In multiplayer it is possible to pick up another computer map after dying and respawning.
