Now, the game is getting a free demo on Steam today (June 6), and shortly afterwards on Xbox One (June 9) and PS4 (June 12). The demo allows you to sneak around the game's tutorial level. If you decide to purchase the full game after completing it, your progress will carry on to the full version.
Styx: Shards of Darkness will be available at a discount of 40% until June 12. If you are yet to sneak around as Styx, here is your chance.
