Requiem

Requiem (REQUIEM.WAD) is a 1997 megawadfor Doom 2 that contains 32 new levels, uploaded to the idgames archive on July 4, 1997. Several of its designers previously worked on Memento Mori and Memento Mori II. It is famous for popularizing architectural tricks that are used even today, including the faked 3D bridges originally introduced by Dystopia 3. It is also one of the few PWADs that are allowed to be used in Compet-n speedruns. This mod was one of the ten 1997 mods to feature in the Top 100 WADs of All Time on Doomworld!
