We're already seeing some cheap Call Of Duty: Advanced Warfare deals mere days after launch, and this one is a corker. At £31.90, The Game Collection's Rakuten marketlace listing is probably the cheapest you'll find it this side of Black Friday.
Make sure to use voucher code MSERAK10 for the extra discount! You'll need to make/have a full account, as guests can't redeem vouchers (those clever so-and-sos!). Brendan's review praises the game as a return to form and a new paradigm for multiplayer funtimes, and I agree entirely, though identifying friend from foe can be a right old pain. Many thanks to oUkTuRkEyIII @ HUKD for spotting this excellent deal, and Chanchi32 for posting the voucher code!
