If you enjoyed the free-roaming FPS with all sorts of incentive to play with your buddies, you'll have to circle a certain date on your calendar.

Today, 2K Games has confirmed that the highly anticipated Borderlands 2 , in development at Gearbox Software, will launch for the PlayStation 3, Xbox 360 and PC on September 18 in the US. UK gamers will get it three days later on September 21.

And as you might expect, there will be pre-order bonuses. Dropping your deposit on this sequel will net you the Gearbox gunpack, which features starter golden guns, plus a golden key that unlocks a special chest in the city of Sanctuary. There's even a Vault Hunter's Relic, which boosts a player's loot-finding capabilities.
