Saving Private Sheep 2 £0.69
A game based on sheep fighting wolves in fierce combat actually exists – and is popular enough that we're getting this Retina Display-ready sequel. The bad guys in question this time round are a bunch of sneaky foxes, who you must dispense of by taking command of the mighty General Sheepard and his catapult. A level creator and a host of gadgets should help to keep things fresh in the long fights ahead.
