So, what's Borderlands 2 all about then?

2K Games has released a seven minute long Borderlands 2 trailer that explains pretty much everything about the game.

Via the narration of one Sir Hammerlock, the trailer takes us through every aspect of the co-op shooter, from the world of Pandora to the classes, from skills to Badass ranks. No stone is left unturned.

There's lots of gameplay in there, too, including of the split-screen co-op, which you can take online.

The Gearbox-developed shooter launches on Friday, 21st September 2012.
