Fields of Hell will have multiplayer mode via zandronum (Doomseeker) but the maps will not support deathmatch mode a video about a gameplay playing in cooperative.
Note: the multiplayer with Doomseeker is not compatible with Gzdoom, to play in multiplayer you will need the source port zandronum 3.0.
