Klei Entertainment, creators of the game Don't Starve, has revealed a trailer at E3 2016 for a new game called Oxygen Not Included. Oxygen Not Included will be a space-colony simulation game where you manage your colonists and help them dig, build, and maintain a subterranean asteroid base. According to the game's page on Steam, "you'll need water, warmth, food, and oxygen to keep them alive, and even more than that to keep them happy."
Oxygen Not Included is set to be released sometime late 2016.
