Description[]
In Dooms I and II, Lost Souls were originally intended to bounce elastically off floors and ceilings when they hit them.
Why it works[]
Due to a coding error, the bouncing test was performed after the Lost Souls' momentum was set to 0.
Trivia[]
In Ultimate Doom, Final Doom and Doom 95 this bug was fixed, causing many Doom II v1.9 demos to go out of sync.
