The Eye-ful Tower Defence: Sanctum

There's increasing amounts of interesting UDK stuff trickling out. I haven't had a shot at this, but it's conceptually pure enough to appeal. Sanctum is another mod-turned-stand-alone, and it's basically a tower-defence game in first person. This immediately makes me think of the late 90s wave of action/strategy games, which of course makes me somewhat fuzzy and nostalgic, before that warm feeling gets crushed with a crushing sense of age, obsolescence and ever-encroaching death. You can download it from here, follow its development here and watch its trailer below...
