A date, not an exact unlock time
The store confirms a calendar date. We have not verified a global unlock hour or regional release-time schedule. A second-by-second countdown would imply precision that the published information does not support.
What to check on release day
Confirm that the store has switched from upcoming to purchasable, then check the regional price, launch discount, download requirements and official release notes. A scheduled date alone is not confirmation that the build is live.
Use the latest first-party listing
Pre-release dates can change. If an older guide differs from the current Steam listing, use the current listing and record when it was checked.
