Announced last week, the Killzone Trilogy box set combines Killzone 2 and Killzone 3 with a high-definition PS3 remaster of the original Killzone. Today we take a closer look at Killzone HD, and the challenging new trophy set that comes with it.

Originally released for PlayStation 2 in 2004, Killzone tells the story of Jan Templar, an ISA Captain whose home planet comes under attack from a Helghast invasion army. Together with a hot-headed sergeant named Rico, a deadly Shadow Marshal known as Luger, and the half-human, half-Helghast spy Hakha, Templar must attempt to reactivate the Orbital Defense Platform and drive the invading forces from his planet Vekta.

This rip-roaring introduction to the Killzone universe has been remastered in HD for inclusion with the Killzone Trilogy bundle. Featuring a single-player campaign with four playable characters and an offline multiplayer mode against AI opponents, Killzone HD has received a thorough audiovisual overhaul: the game boasts 720p graphics at a steady 30fps, with MSAA filtering, sharper textures and higher quality sound effects. But don’t take our word for it – check out these crisp HD screenshots:

In addition to these improvements, Killzone HD has been enhanced with a full set of trophies. The trophy list is detailed below (beware of spoilers if you’ve never played the original Killzone).
