Dead by Daylight/Friday the 13th
We're going to start this list a little loosey-goosey, but there's a good reason for it if you're a PlayStation fan. PlayStation Plus has been a great resource for horror games lately, as the marquee game for September 2018 was Dead by Daylight and October's is Friday the 13th. These are both similar, asymmetrical multiplayer that pit a group of players against one other who plays the role of a killer of some sort. Friday the 13th is likely on its way out of relevance, due to some legal troubles, so this might be the game's last hurrah.
