Not quite what the topic says, but the team behind the Doom 3 TC The Ruiner have finally unveiled their remarkably non-ruined website. I couldn't even find any broken links. Anyway, The Ruiner is the second TC by the same people who brought us the fast-paced Abuse-like Quake 4 mod HardQuore.
Ruiner is a dark, nightmarish, fast paced third person action modification for Doom3. the player fights hordes of the damned using unique weapons, abilities and spells.
The website features an impressive resource of media demonstrating the TC and as if that wasn't enough, they also talk about a coming demo being released sometime during this winter. Don't just sit there, get over there now.
