Killzone Trilogy is a collection of 3 great games, but with only one title being the reason to buy, I can only recommend it if you do not own Killzone 2 and 3. If you do own them, but you still want to play the original, you can save money and download it by itself on the PlayStation Store. With nothing added to the other games and a rather lackluster upscale treatment to the other, this collection seems only for those who have never experienced the series.
SummaryThe Killzone Trilogy is a compilation pack that includes the original Killzone, Killzone 2, and Killzone 3, as well as all the multiplayer packs for Killzone 2 and Killzone 3.
