Hard work pays off. Create your very own Overwatch game modes in the Workshop!
Build. Play. Share.

The Workshop is live now on PS4, XB1, and PC. We’ve seen more than 2.7M games created in the Workshop since PTR and more than 60,000 game codes shared, but we can’t wait to see what the community comes up with next.

Key Features

  • Create your own scripts for customized game modes in Overwatch
  • Share/link out to your own game mode without navigating through menus in game
  • Debug issues with your scripts using the Workshop Inspector
  • To access Workshop and start creating a script, while in game, click Play > Game Browser> Create > Settings > Workshop.
