In 2012, there was speculation floating around over an ambiguous Valve collaboration with Adult Swim involving “Team Fortress.” Writing for Polygon, Michael McWhertor suspected it was a TV spin-off, and so did Eurogamer’s Jeffrey Matulef. As Matulef wrote in an update, however, it was simply an in-game hat. That wasn’t the end of it, though.
Adult Swim later aired a commercial that was essentially “Venture Bros.” meets “Team Fortress 2.” It turns out that McWhertor and Matulef were correct in their assumptions, but sadly, the series never came to be.
According to a video produced by Tyler McVicker, the show was in development from 2012 to 2013, but because of “Valve’s inability to work with third parties, meet deadlines, and have adverse reactions to limits and guidelines,” the project lagged. Unfortunately, because the two companies were having compatibility issues and Valve failed to follow directions and deliver content on time, Adult Swim decided to terminate the project.
While the TV series may have fallen through, at the very least, “Team Fortress 2” did make it to Adult Swim through “Robot Chicken.”
