Aquatic horror gamers won’t have to wait long for their next dip into the deep blue, as after six months of development in Early Access, developer Embers and publisher Oro Interactive have announced that Murky Divers will be exiting the service on Steam and launching in full on December 12. The 1.0 release will introduce new creatures to the game, a new playable biome and more. And because it’s that time of year again, there will be a Christmas theme with free-to-keep cosmetics.

Murky Divers puts you or as part of an 8-person team to take a trip down to the bottom of the ocean. Your mission: Remove all corpses from Pharma Corps’ abandoned labs, and erase any evidence of their failed experiments. It’s never that easy, of course, as you’ll need to deal with things lurking in these wrecks, and oxygen might run out quicker than you expect.
