The idea for this PWAD came from iddqd.ru. The main concept is: you should create a level using only two IWAD textures and two IWAD flats. Thanks Shadowman for inspiration.
PrBoom-Plus 126.96.36.199+ or (G)Zdoom are recommended.
WARNING #1: You should not use glboom at all and glboom-plus before 188.8.131.52 with this PWAD to avoid HOMs.
WARNING #2: You should disable "Try to emulate intercepts overflow" setting in PrBoom-Plus (overrun_intercept_emulate 0 in cfg), because there is a place where this overflow will happen permanently with all the ensuing consequences (semi-noclip)
MIDI: Equinox. Sounds: Power Slave, Half-Life, Doom3.
Dehacked patch, in-wad demos and PWAD composing: Andrey "entryway" Budko.
