The Vita’s library of just over 240 games is quickly approaching a
dangerous level. When you add in the plethora of downloadable versions
of older games, there is plenty to choose from, but there are still only
a handful of games that really use the Vita’s functionality to its
fullest. Killzone: Mercenary does that, and offers a competent and impressive FPS as a result, complete with all the tropes of the genre.
It’s just a shame that it feels likes half of a really good game.
