A 17-minute video by YouTuber decino explains the movement and attack algorithms of Doom's monsters using annotated source code from the officially released and open-sourced Doom engine, demonstrating the game's underlying AI systems.

For all these times we talked about Super Mario https://unsung.aresluna.org/tags/super-mario-bros/ , we never covered another important game, Doom.
