Shrine combines two great tastes that taste great together: Doom 2 and eldritch abominations. It wraps these in a foggy atmosphere whose pastel palette manages to evoke a good amount of creep factor thanks to a unique artistic style and gross monster designs.
The mod was created by someone who calls themselves scumhead, which I think sells them a bit short considering how great this mod looks. While it’s recognizably running in the Doom engine, the whole look of the thing has gotten a true overhaul. There’s almost an Edward Gorey style to the linework in the pixel art here, and the muted colors convey a sense of otherworldliness that works with the Lovecraftian theme very well.
There’s also a suggestion of Silent Hill 2 in here, with vaguely evocative creatures that pull at something just beyond the tip of your brain. The weapon designs are great, too – there’s a double-barreled shotgun that seems wired up to your arm, what looks like a canned alien brain, and other things that look like they’ve been fashioned out of the beaks and claws of various abominations.
