Doom 404

Doom 404 is a 32-map megawad for Doom II created by Adam Windsor. It was named one of the runner-ups at the Cacowards in 2018.

The name 404 is both a pun on the IT help-desk theme of the maps and Windsor's use of at most 404 linedefs per map. Thus it's a collection of small maps, similar to Windsor's megawad from 2000 called Demonfear.
