Direct answer
Yes—Windows PC on Steam is confirmed.
The official Steam product is WARDOGS App 1867240. On August 27, 2026, it was still marked upcoming, so a Store listing or preorder did not mean the main app was already publicly playable.
macOS and Linux are not confirmed by the current Steam platform fields.

Use the live Steam page to see whether the main app is available to install. Keep the main App and the separate historical Playtest client distinct.
System boundary
Only Windows is currently listed
On August 27, 2026, Steam listed Windows support and did not list macOS or Linux support. That is a dated store-state statement, not a permanent claim about future development.
