Diablo III: Reaper Of Souls pre-order| GMG | £22.99 (save £2 vs Gamestop)
Diablo III's first major expansion is now exactly a month from release, adding a new campaign and introducing a terrifying new enemy in the form of fallen angel Malthael. Unlike the fairly useless Tyrael (who transformed from an epic sword-wielding legend into a... bald guy), the Angel Of Death is at the height of his powers, and leads a horrific crusade to steal the Black Soulstone for himself. With new enemies, classes and environments to get to grips with, there should be a decent slab of game here, and Green Man Gaming are making with the savings. Note that you'll need the base game to play - and that the auction houses are set to close in a matter of weeks.
