A Swedish horror game studio. Check out our latest project:
“Apsulov – End of Gods”

APSULOV is a first person dark adventure/horror game where Nordic creatures and gods are combined with science and technology to create a horrifying new world!

Visit www.apsulovgame.com for more information about the game.

You may think you know your limits – what evils you might be willing to commit to save yourself.
But are you ready to find out what you are capable of? Are you brave enough to face the darkness in your soul?
Not only are the old stories true, but the things that crawl in the shadows are more wretched than you could have ever imagined.

The whispers of the northern woods pick at your sanity. Your fingers tremble as you light your final match, body shivering of dread. Do you sense them hunting for you? Can you feel them hunger for your last breath?
