Fall Guys: Ultimate Knockout is a massive multiplayer experience that plays out much like Wipeout or Takeshi's Castle. The game is only on PS4 and PC right now, but developer Mediatonic has shown interest in bringing the game elsewhere.
An official FAQ for the game on Mediatonic's website includes a Q&A, and one of the questions includes a request for the game on Xbox or Switch. You can check out the team's official response below.
To start with, Fall Guys will only be available on PS4 and Steam. We'd love to bring the game to other platforms further down the line. Please let us know on Twitter and Discord which platforms you'd like us to release on next - we'd love to see how much demand there is!
