Killer in the Cabin is now officially available on Steam, offering a co-op social deduction game for Windows developed by Games People Play (obligatory Spinners link). The game focuses on a group who survive a bus crash in a remote location and must remain in survival mode, as it turns out one of them is a killer. Here's a launch trailer with some painful exposition. Here's more:

In Killer in the Cabin, play as a member of a group of survivors from a bus crash in the desolate Norwegian mountains, where in order to survive you must work and communicate together in order to gather supplies, discover shelter and share food as you wait for help to arrive. Stick together and you’ll make it out alive, but danger looms. In each match of Killer in the Cabin, one killer is chosen who must eliminate every other party member while avoiding detection. If allocated as the killer, use the sandbox environment to get creative as you terminate your fellow survivors. When the party begins to suspect who the killer is, they can vote and kill the elected suspect, whether they are guilty of the crimes or not. With 15 minute long game sessions and multiplayer play with up to 8 players, Killer in the Cabin puts players’ communication, deception and truth-telling skills to the ultimate test.
