The "Outlast" franchise is on sale for up to 85 percent off on Green Man Gaming as past of their "Werid & Wonderful" sale until April 8, 2019. Here's a list of those deals:

All of those titles requires a free Steam account to activate and play. Outlast: Whistleblower requires the base Outlast game to play.

Outlast features an outstanding creepy atmosphere. I spent a lot of time taking in the unique dreadful sights.

It was refreshing to face frightening monsters that can't be killed. The only thing that I didn't like about the game is its terrible final chapter.

Whistleblower is the perfect DLC for Outlast that features an interesting narrative. Just don't expect original environments to explore.

I haven't played Outlast 2, but I've heard that it's a lot more open and longer than the original, with an ending that will give you nightmares.
