Light amplification visor



The 'light amplification visor' is a powerup that appears as a pair of gray goggles with blinking red lenses. Picking one up will show everything at full brightness for 120 seconds. When 5 seconds remain, the display will begin blinking back to its original light level, signaling the end of the visor's effects. In Doom 64, instead of blinking the added light effect simply fades into the current lighting (or lack thereof) when the power up runs out.

Light amplification can also be activated with the cheat code idbeholdl.

Light amplification visors are the rarest of Doom's powerups, as they undo the various lighting effects that are an integral part of the game's atmosphere (although four can be found in E2M6, and three in MAP10 (Doom II)). In Ultra Violence they appear in only 11 unique maps throughout Ultimate Doom, Doom II and Final Doom.

Light amplification visors are included in the items percentage displayed at the end of each level.



Light amplification visors originally used colormap 33 in the press release beta to simulate night vision goggles.

Many players have lamented the replacement of the light amplification visor in Doom 3 with the flashlight, as the player cannot use the flashlight and another weapon at the same time.
