Blizzard sent out the following
Overwatch players, modders, and budding game developers can now create games in ways previously unimaginable with a new feature—Workshop! Within Workshop, players can create a Script to add Rules and unique play Conditions on top of the established Overwatch game modes they already know and love. Rules can do many things, like change how a hero’s movement and abilities work, modify how players are damaged or healed, or even display text under certain circumstances. Games created by Workshop will live on the Custom Game Browser.
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 their scripts using the Workshop Inspector
  • Workshop will be available on Console and PC

Workshop is now available on the Public Test Realm (PTR) on PC. To access Workshop and start creating a script, while in game, click Play > Game Browser > Create Settings > Workshop.

The Overwatch team is offering two new game modes created through Workshop to give players an idea of what’s possible:

  • Molten Floor: Stay off the floor, it’s deadly lava.
  • Mirrored Deathmatch (FFA): Players wage deathmatch as the same mirrored hero, rotating heroes every minute, the player with the most kills wins.
