Killzone: Mercenary follows on from a long string of games that have unsuccessfully attempted to bring console quality gameplay to Sony’s PlayStation Vita. The first person shooter genre has become particularly notorious for failing to translate, and Nihilistic Software (who were responsible for a bad Resistance game and an even worse Call of Duty) are likely to have tainted the expectations of anyone who played either of these two titles. How does Killzone handle the downsize? In three words? Better than most.
