2K and Gearbox Software today announced that the Borderlands 2 Ultimate Vault Hunter Upgrade Pack is now available via digital download across all available platforms. The new downloadable content pack will increase players’ level cap from 50 to 61, as well as unlock a third play through of the game via the Ultimate Vault Hunter Mode, and a new pearlescent-colored weapons tier, the rarest on Pandora.

With over 55 editorial awards and nearly six-million units sold-in to date, 2K and Gearbox are celebrating the critical and commercial success of Borderlands 2 and thanking their most passionate fans by including the Ultimate Vault Hunter Upgrade Pack as part of the Borderlands 2 Season Pass. The pack can also be purchased individually for $4.99 (400 Microsoft Points).

"Millions of vault hunters have spent countless hours adventuring their way through the Borderlands 2 universe," said Randy Pitchford, president of Gearbox Software. "Raising the level cap takes a significant amount of man hours, but we know fans are eager to continue looting Pandora, and so we’re rewarding our Season Pass holders by offering the Ultimate Vault Hunter Upgrade Pack for free as a part of the celebration."
