Ready for a post-Christmas treat? GOG.com is once again offering a free game for the next 48 hours. This time around, it’s Frictional Games’ 2015 oceanic horror epic, SOMA!

Right now, all you have to do is log in or sign up at GOG.com, then click on the banner at the top of the screen, and boom, SOMA is yours. And while you’re there, why not check out some of the other deeply-discounted deals that GOG.com is offering during their Winter Sale? You can find some cool deals on classic and more recent horror and genre titles, including Frictional’s own Amnesia: The Dark Descent, Blood, BioShock Remastered and BioShock 2 Remastered, Darkest Dungeon and more!

Released in 2015, SOMA is also available (though not for free) on PlayStation 4, Xbox One and Steam.
