2K Games' distributor Gem is running a number of promotions in support of Borderlands 2.
The firm (which has also worked on the 'Guns, Guns, Guns' Top Trumps pre-order campaign), is running a Facebook competition. Simply by liking the GemGroup page, you can win an Xbox 360 250GB Console and a copy of Borderlands 2. Winners will be picked at 4pm.
Gem has also invited professional spray-can artist, Mr. David Gnash, to create a 6ft by 5ft graffiti canvas of Borderlands 2. The canvas will be donated to GamesAid for next year's charity auction. You can view the progress of the canvas throughout the day on the firm's Facebook page.
