Publishers 2K will be releasing a set of limited edition Borderlands 2 Top Trumps cards as part of a pre-order incentive at selected UK independent retailers.
There will be other pre-order incentives with the big retail chains such as Game, but independent stores will get cards that feature 30 of Borderlands 2's weapons. There's only 5,000 packs of cards to be dished out across the country, so it's strictly a first come, first served deal.
As well as this, 2K and Gearbox Software have also released a "de-make" of the game which can be played by browsers for free now. You can check that out here.
