Overview
- PC uses a single worldwide unlock across Steam and the Epic Games Store, going live Sept. 11 at 12 pm ET, 9 am PT, 5 pm BST, and 6 pm CEST, with Australia at 2 am AEST on Sept. 12.
- PlayStation 5 and Xbox Series X/S versions follow rolling midnight local releases on Sept. 12, resulting in different regional start times by time zone.
- The Nintendo Switch 2 edition arrives Oct. 3, extending the staggered rollout across platforms into early October.
- Borderlands 4 was moved up from Sept. 23 to Sept. 12, with CEO Randy Pitchford attributing the change to development readiness and bug-fix metrics rather than competing releases.
- Cross-play support may briefly split friends by platform on launch day, and there is no early access tied to deluxe editions.
