Killzone: Mercenary

Mercenaries will anything for a price, but if you're a Killzone fan, you might pick up this Vita game just because it looks to be a solid entry in the series.

As is befitting of the title of the game, you take no sides in the ISA/Helghast war, but will do anything for a price. As such money is important in the game, and it's what you earn for good kills and combos, and it's what you use to bolster your arsenal.
