Playing multiplayer co-op levels in Brutal Doom. Used the Zandronum Doom port (found here: http://zandronum.com/) which adds a very useful launcher interface for creating and joining multiplayer servers. It supports ZDoom, GZDoom and Skulltag mods, as well as allows the use of GZDoom’s OpenGL renderer for some seriously improved visuals and effects.
I am not 100% sure of the names of these maps, but they are definitely a lot of fun to play.
