Borderlands 4 is a 2025 action role-playing looter shooter developed by Gearbox Software and published by 2K, launching on September 12, 2025, for PlayStation 5, Windows, and Xbox Series X/S. Set six years after Borderlands 3, the game follows new Vault Hunters—Rafa, Harlowe, Amon, and Vex—on the planet Kairos, where they join the Crimson Resistance, led by Claptrap, to overthrow the despotic Timekeeper and find the planet's Vault. Gameplay features a seamless world with no loading screens, new vehicles, and a grappling hook, supporting solo or four-player cooperative play. The narrative involves gathering allies like Rush and Zadra to defeat the Timekeeper's lieutenants, and the game received generally favorable reviews from critics. A Nintendo Switch 2 version was announced but is indefinitely paused, while upcoming story expansions will add new playable characters like C4$H and Loveless.
