Overview
Doom 64: Unseen Evil is a mod for GZDoom that brings the atmosphere of Doom 64 to the worlds of Doom and Doom II. Everything is entirely overhauled: from the player and their weapons, to the halls and the demons that stalk them.
All of the demons that were absent from the original Doom 64 have finally emerged from the deepest pits of hell, including the unsettling Revenant and the sinister Arch-vile. If you're looking for a new challenge, the exclusive Redemption Denied difficulty will bring some of the crueler monster placements from PSX Doom into the vanilla Doom maps.
Proceed with caution; there are many evils yet unseen.
Unseen Evil fully supports the original Doom and Doom II levels, as well as any community mapset that uses the vanilla texture set. Any textures that are new or replaced by a community mapset are not taken into account by the Terraformer, which can make things a little screwy in terms of visuals. Select mapsets at your own discretion.
Doom 64: Unseen Evil requires GZDoom v4.12.2 (or higher) and a copy of Doom or Doom II.
