They added the piano to the Overwatch Practice Range by June 15–16, 2026, based on posts and clips discussing the new feature around that date.

What’s known

  • A June 15, 2026 post refers to the Practice Range piano as newly added.
  • A June 16, 2026 Reddit post says the piano was in the room above the gym area connected to the catwalk.

Small caveat

The exact minute or patch note isn’t clear from the public posts I found, but the public discussion points to mid-June 2026 as the addition window.
