There are no monsters here; but your buddy came down with Doomentia, must be hunted down, and killed. By the way, he will be hunting you too...

Doomentia (abbr. Dmt, dmt, DMT, and so on) is a small group of Argentine DOOM players from the City of Buenos Aires and vincity. The DMT site provides or presents demos and multiplayer add-ons made by the group members, gives information on Doomentia related LANs or activities, and generally promotes dedicated DOOM playing. Argentinians (or any players living close enough to Buenos Aires) are invited to contact the group to play and whatnot. You can use dmt.webhop.net to conveniently access the Doomentia pages.
Doomentia members usually play classic DeathMatch or Cooperative games amongst each other privately, using version 1.9 (or 1.9 with longtics) of Doom over Kahn v1.3 (and previously MS ZoneIPX), though some of them may occasionally be found on public released source based engine servers, usually with the group tag before their nicks. Presently Doomentia consists of three people: myk from Coghlan, [W4GH4X] from Avellaneda, and neurotiko from Boedo. To watch some recordings between the members head over to the DeathMatch demos section.
To contact the Doomentia team, you may simply send an e-mail message to email@example.com, making sure it contains the word "doom" in the subject line, or the message will be filtered and might be lost.
