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 all unexplored lines in the current level (excluding those flagged not to appear) to be shown on the automap in gray.

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

Computer maps last the duration of the level where they are picked up.

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.
