Trapped in a makeshift maze by a mysterious adversary, you must run a gauntlet of macabre puzzles and challenges to reach safety. Equipped with only a flashlight, surviving this tightly-focused exercise in fear will require creative thinking, steady nerves, and a strong stomach.

Because surprise is such a large part of what makes After You effective, Sum and the team won’t be giving away too much. They are only willing to reveal that After You is designed to be deeply disturbing, forcing players to consider the meaning of their own choices and to question their motivations.

On the question of why he would choose to make a horror game, Sum said: “I’ve always tried to understand the things that scare me, and making games is a great way to do that. I can’t handle anything horrific – movies, games, or anything – so that intrigued me: why do so many people enjoy these things that are inherently unpleasant? So I started making a game in a genre that terrifies me. It’s extremely uncomfortable to test my own game, just designing it has been giving me nightmares. How messed up is that?”

After You will launch on Steam for PC and Mac, with launch date and more details coming soon.
