PWAD file for E1M1.|
Designed from the ground up for deathmatch. Most actions/acquiring of a weapon cause a sound so you generally know exactly where other players are based on the sounds they're making.
It's been played for (thousands of) hours with two player deathmatch - it may be a bit small for 4 player deathmatch.
