By GuestBloodlands is a set of 32 DOOM II Deathmatch-only levels from TeamTNT. It is now available on ftp.cdrom.com and its mirrors. See below for the exact path.
We tried to pay attention to deathmatch in Icarus: Alien Vanguard, but there's no substitute for dedication. Bloodlands is all deathmatch, all the time. We have small levels for tight, high frag-count mayhem, and larger ones for more players and for the folks who like hunt-and-seek deathmatch. But in every case it's going to be a fun time.
You wondered what happened to the weekend when you played Icarus. You'll wonder what happened to the month when you play Bloodlands.
