To celebrate Gears of War 3 release this week, we've teamed up with Calibur 11 to give one luck reader a customised Gears of War Vault case for the Xbox 360 Slim. As well as protecting your console from damage, the Vault also has a special LED add-on that'll light up the Gears logo on the case's side.
To be in with a chance to win, simply head on over to our competition, answer the question correctly and supply your full contact details. A winner will be drawn come the competition's close on Friday 23rd September at 5pm.
You can check out more Calibur 11 goods on the company's official website.
