Full brightness is a multiplayer cheat which causes the screen to always be rendered at full brightness. The effect is similar to the lite amp power up, but permanent. This is considered a cheat as it gives the cheating player an unfair advantage over other players: in dark areas, the player will be able to see opponents perfectly.

The cheat takes the form of a PWAD loaded at startup or a modified IWAD file, to change the COLORMAP lump. Each light level map in the colormap is changed to be equal to the full brightness colormap.

An alternative method is to repeat and duplicate the first 16 colormaps two times each (or the first 8, four times each), thereby dramatically increasing the brightness of the game, while still allowing the player to partially view spectres and players using the blur artifact: Due to partial invisiblity using the colormap to make these partially invisible, a totally remaped colormap makes them almost totally invisible.

The only conclusive way to detect the use of this cheat is visual observation of the player's screen as the game is played. However, on maps with extremely dark areas, viewing deathmatch recordings in which the cheat was loaded by one of the players could reveal circumstantial evidence.

A related multiplayer cheat is done by editing the executable file with DeHackEd (or other doom exe editor), and giving the player objects "full brightness" (causing their sprites to always be rendered on colormap 0). If done properly, this would generally not cause consistency failures and would dramatically increase the visibility of other players.
