ENDOOM - NicheInterests/mistfunk GitHub Wiki

No fan-made level for iD Software's 1993 pioneering FPS Doom can be considered complete without displaying a bespoke 25-line ANSI art screen shown when the game is finished and returns the player to the [MS-DOS] prompt. (Modern players not playing in MS-DOS may fail to see the screen at all.) That is the ENDOOM (END of DOOM) screen, and a small isolated community of naive ANSI art practitioners have kept a tiny flame burning for ANSI art to use it in this very specific context, independent (like ZZT designers) from all wider ANSI art practice.

An incredible gallery of earnest and occasionally virtuous efforts from the ENDOOM community can be enjoyed via https://www.doomworld.com/forum/topic/130123-endoom-appreciation-thread/
