Indie developer Mike Maulbeck threatened Valve's Gabe Newell over a mistake made on the Steam store regarding his recently-released game, Paranautical Activity.

According to Kotaku, Maulbeck sent out a rash of angry tweets on Oct. 20 with regard to a mistake made in listing his company's game, Paranautical Activity, as an early access title when it was recently completed and therefore out of Early Access. As a result of the following tweets, the game was pulled from Steam entirely.

Maulbeck has since posted to the Code Avarice (his development company's) website on Oct. 21, announcing that he is leaving the company. He said, "I’m really, deeply sorry that my short sighted, hot tempered actions resulted in not only my own dreams and aspirations being destroyed, but those of the entire team I worked with. I’m sorry that my statements made Valve and/or Gabe uncomfortable and upset (rightfully so)."

He also touches a bit on how he's used Twitter as a tool to vent his anger ever since starting out in the games industry. It is his hope that, by stepping down, Code Avarice's games will be allowed on the Steam platform once again. As for what he plans to do in the meantime, Maulbeck succinctly said, "I'm out."
