Wolfenstein: The New Order on PC is super hot for £10, especially for the Occupied Edition, which comes with a 20-page tour guide of occupied Britain and some postcards. You'll find an invite to the upcoming Doom beta too. This is currently £3 cheaper than the standard version.
Wolfenstein: The New Order has a huge shout at my Game of the Year pick thanks to providing a classic bombastic old school shooter experience. There's an outstanding stealth game in there too if you fancy being a bit sneaky. Fantastic replay value is offered by multiple routes, unique skills and loads of treasure to reclaim from the Nazis. The story is way better than I expected too, with a pleasing mix of emotions and grin-inducing one liners. More of this please!
