While this has been a little cheaper in the past, the current deal from Sainsbury's is still worth pointing out. Overall you can save yourself over £6 compared to the next best offer.
343 Industries have done a good job bringing the original Halo in glorious HD, showing that the game that proved FPS’s could work on consoles is still as enjoyable today as it was a decade ago. The multiplayer may be a little lacking overall, but for a tenner this is still worth a look. Thanks to oUkTuRkEyIII @ HUKD!
