Borderlands 2 is finished, some 60 days before its release date. Developer Gearbox Software announced today that development on the project has come to a close, with the first-person shooter now headed to certification for release on the PC, Xbox 360, and PlayStation 3 on September 18 in North America and September 21 internationally. It's unlikely Borderlands 2 will miss its release date.

Now that development on Borderlands 2 has wrapped, Gearbox is shifting its focus to post-launch content for the game. The team is currently working on the Mechromancer character class, which will be released as free DLC about 60-90 days after launch for members of the Borderlands 2 Premiere Club. Gamers can score access to the Premiere Club by preordering the game.

Borderlands 2 is the sequel to 2009's well-received loot-based co-op shooter. A recent game guide writer's playthrough of the title took 58 hours, with Gearbox calling the game a "hobby." For more on the title, check out GameSpot's latest preview.
