Gears of War is the sequal to the greatest exclusive game available on the 360, so it needs no introduction and the shotguns have just been updated recently to make online battles even better on top of great modes such as the Horde.
Anyway, if you haven't already bought this game, then the chances are you've already become an outcast with most of your Xbox Live friends and now's the time to take advantage of the game, as the price has just been lowered to £32.99 including free first class recorded delivery and comes with a free magazine that has a £3 voucher for future orders.
Don't forget to go through Quidco to receive 4% cashback to make this an even better deal, coming to a total cost of just £31.67 all inclusive.
Hope that helps. :)
