The recent console versions of Shadow Warrior have stayed around about the £30 mark since its release, but this offer from The Game Collection is one of best we've seen so far. It beats the next cheapest offer by around £2 on both consoles.
Jon said that Shadow Warrior was "still as savagely brutal, tough, slick and satisfying as ever" in his review, as the fight against armies of demons is just as fun as it was in the original PC release. It's definitely worth a look if you haven't played it already, or if you don't have a PC capable of playing it (as well as the saving, as the PC version tends to be far cheaper these days.) Thanks to oUkTuRkEyIII @ HUKD for the heads-up!
