Step into a dungeon, take a left at the creepy skeleton, and say hello to Bloodwych, the 1989 DOS game that proves co-op first-person dungeon crawling can be both confusing and oddly addictive. It's got split-screen multiplayer (yes, really) and color-coded mages who look like they've just come from a low-budget wizard convention. The game lets you talk to NPCs, though half of them respond like they’re holding in a sneeze. Don’t expect hand-holding—expect to die, get lost, or accidentally drink something that makes you glow. But if you love old-school challenge with a side of weird, Bloodwych is a cult classic worth spelunking into.
