The PC version of Joe Danger 1 and 2 will feature content from Team Fortress 2 and Minecraft (in Joe Danger 2 only), to allow some interesting levels.
According to Hello Games manager director Sean Murray, "Just for fun Aaron started adding TF2 characters into Joe Danger and I was in love with how good they looked. We completely had to make them happen for real, so we called Valve, and now it's a real thing! Is this the first time Minecraft is on Steam? Is this legal?"
The Joe Danger titles will be available on Steam on the 24th June 2013.
