It’s official, Outlast for Mac is now available. The game was released on March 31, 2015, and joins Shadow Warrior as the biggest macOS releases this week. The news comes directly from developer Red Barrels, who made the announcement via Twitter last Friday.

Outlast is a first-person survival horror game that was first released for Windows in September 2013. And to many, this is one of the scariest games on Mac.

The game puts you in the role of a freelance journalist who decides to investigate a psychiatric hospital lost in the mountains of Salt Lake County, Colorado. That was obviously a bad idea, as hell breaks loose and you find yourself alone in a nuthouse full of homicidal patients.

To make matters worse, you are completely incapable of combat. With no weapons at your disposal, you will have to be quick on your feet and smart to stay alive.

Red Barrel is also bringing the game’s first (and only) DLC, Whistleblower. Outlast: Whistleblower serves as a prequel and shows you events from before and after the main plot.

Overall, most reviewers really enjoyed the PC version of the game, with IGN concluding in their review that:

Outlast can stand proudly as a unique and terrifying survival horror game. Unlike many modern horror games, it remembers that the most frightening monsters are those that you can’t kill, but have to flee from, and it creates an outstandingly creepy atmosphere that rendered me defenseless against its many well-paced jump scares.

Needless to say, Outlast is a must if you enjoy horror games. I can’t say I’m a big fan of the genre, but you can expect a gameplay video very soon. In any case, the tension in this game is so high, you will want to play it with the lights on!
