Project Slipgate

Project Slipgate is an 11-map set for Doom II and the ZDoom source port, created by Bryant Robinson (Gunrock) and Kevin Robinson (The Solution) and originally released in 2001. The set is heavily influenced by Quake and also by , the former in particular providing much of the texture work and atmosphere. The initial levels are set in tech bases before moving on to a demonic dimension heavily inspired by the later levels of Quake. The set received a spin-off, Dissolution, in 2002.

In 2021, Gunrock released Project Slipgate: Remastered Edition, which despite the name is a remake of the project containing fewer maps. Despite this, it replaced the original /idgames archive release, making the original unavailable on that platform starting from 2021.
