I played an interesting horror game called Monstrum on the PC. This feels like a stripped-down, procedurally generated version of Alien: Isolation set on a container ship. It also has hints of The Ship, a jolly little multiplayer game based on Agatha Christie novels, which I found strangely compelling and unsettling.
Monstrum has almost no back story: you start in a room on the ship, and you collect a number of objects to help you escape. Also on the vessel is one of three monsters: a ghosty thing, a sort of transluscent Alien with a flower for a head, and a hulking demon that looks oddly like Horace from Horace Goes Skiing. All are very sinister and want to kill you. And that’s more or less it. You creep around looking for parts, hiding and avoiding death. As per Alien: Isolation, you can’t kill the monster and, if it gets hold of you, you’re dead.
The setting is very well realised, and capitalizes on the sinister feel of abandoned ships. Every time you play, the computer generates a new ship, so you can’t learn where the items are. I actually found it more frightening than the better-produced Alien: Isolation, although it’s undoubtedly shallower and there's less to do. I could imagine this game providing a few hours’ entertainment to most people and, given its procedurally generated environments, a lot of entertainment to others.
