Nioh is one of those games that keeps on giving. If you enjoyed Sekiro and are partial to RPG-style loot, you could easily spend hundreds of hours with this yokai-busting samurai game. It's particularly worth playing if you enjoy co-op in these sorts of games – it's super easy to team up right from the menu.
Outlast 2, on the other hand, is a survival horror game about a cult. It's nasty.
Both of these PS4 games will be available through PlayStation Plus starting November 5, after which point you'll have until December 3 to claim them for your account.
