One of the things that happened during the PC Gaming Show was Klei (Don’t Starve, Mark of the Ninja, Invisible Inc.) announcing their new game: Oxygen Not Included. They released a trailer too:

It’s a space-colony simulation game in which you manage colonists on an asteroid base. Additionally, you’ll have to keep them from running out of food and oxygen and dying- because this is a Klei game.

Currently, there’s a Steam page up and running with a few screenshots. They’ve put down the prospective release date as “when it’s ready!”
