Then there's the Ultimate Loot Chest Limited Edition. It's even more lavish, costing $149. It contains all of the Deluxe Hunter items plus a collectible scale replica of the red loot chests found within Borderlands 2. A steel case, Creatures of Pandora ID chart, postcard set, field notes from Sir Hammerlock and a cloth map are also included. Each comes individually numbered.

Both special editions are available for PC, PlayStation 3 and Xbox 360 versions of the game.

Pre-ordering either of these at select retailers will give you entry to the Borderlands 2 Premiere club, allowing you to nab the following in-game items: the Gearbox Gun Pack, a Golden Key, the Vault Hunter's Relic and an all-new fifth character class - the Mechromancer.

The Mechromancer will likely launch after Borderlands 2's release, but will come free to Premiere Club members. It will be regular paid DLC for everyone else.
