The test client may remain installed after the server window closes, but that does not mean matchmaking remains available. Early Access is a separate September 10 launch milestone. [steam-beta-schedule]

Plan around the 08:00 UTC cutoff

  1. Convert 08:00 UTC to your local time.

  2. Finish reward claims or recordings before the endpoint.

  3. Keep the commercial release and beta clients separate in Steam.

What remains after the test closes

A service issue or official extension can change the practical endpoint. Check Steam news near the close. [steam-beta-schedule]
