This is the best co-op multiplayer currently out. Period.

Outlast Trials takes the formula of the Outlast games and puts a multiplayer spin on it - and it works. Levels are fun and replayable and constant progression makes it worth revisiting completed Trials. Only downside is the lack of frequent updates. When there‘s an update it is enoumous, but we‘ve only gotten a single one since Early Access release. Hopefully this changes with the full release that‘s coming soon.
