Bioshock Infinite: Burial At Sea Episode Two
Xbox 360, PS3 & PC

Now that Ken Levine – the creative force behind the Bioshock series – has closed the studio that made it, this is the franchise's swansong. In it you play former sidekick Elizabeth, who isn't quite as handy with guns as hero Booker DeWitt, making stealth and smacking enemies over the head from behind your best options. New additions include the ability to see enemies through walls and a microwave gun that makes them explode. Weaving its plot back to the original, this is a fitting ending with satisfying twists and a definite sense of resolution.

Surgeon Simulator
iOS

After around a minute's medical training, which teaches you how to pick up and aim a surgical instrument, your baptism in blood is a heart-transplant operation undertaken solo and without further instruction. The intentional clumsiness of the controls means you'll bludgeon and hack many patients to pieces before stumbling across a way of keeping enough blood inside their haemorrhaging bodies to survive the procedure. Converted from a PC game (and surprisingly not made by the minds behind Goat Simulator), this is just as hilariously brutal on iPad and comes with extra eye and dental transplant ops.

Advance Wars
Wii U

Advance Wars' bouncy, cartoon vision of conflict is actually a 21st-century reinvention of chess. Taking turns with your enemy to move your masses, you have to bear in mind their strengths and weaknesses, the terrain you're attacking on and the intermittently recharged super-power of your commanding officer. This was the first Advance Wars to emerge outside Japan, and while its chunky visuals look ludicrous on a big TV, played on the Wii U gamepad this is just as enthralling as it was in 2002; its battles rely on perfectly balanced mechanisms, rather than the plethora of extra features that cluttered later iterations. This is still one of the best games ever made.
