/vr/ - Retro Games

I'm trying to remember a map pack I downloaded like 2 years ago. The first map takes place on a cliffside and has you go to an island with revenants on top of pillars centered around a base that you eventually go inside of. There's also a battle with a bunch of spider masterminds at the bottom of a giant elevator. I can't think of any other details, but if this sounds familiar to anyone I'd like to try and find it again.
