Announced back at last year's E3 Klei Entertainment's Oxygen Not Included has come a long way. Currently in Alpha, the space colony simulation has players maintaining a subterranean asteroid colony, whilst caring for its inhabitants. Klei are known for their distinctive art style and titles such as Don't Starve or Don't Starve Together. Thus, it's no surprise that over a thousand people have already opted into the alpha for their new project.
Oxygen Not Included will come to Early Access on May 18th. It will cost $24.99, or your regional equivalent, with the mention that owning another Klei title gets you a 20% loyalty discount. Those who've purchased an Alpha key, which are still available for $19.99, do not need to purchase the Early Access version. Head on over to the Klei forums for the full announcement.
