Source: Killzone HD Coming to PSN, Trophy List Revealed - IGNIt was only a few days ago that the Killzone Trilogy was confirmed for PlayStation 3. The Trilogy will include Killzone 2 and Killzone 3 – both native PS3 games – as well as an HD version of the PS2 classic Killzone. The Trilogy is set to come out on October 23rd in North America and October 24th in Europe.
But what about those of us who already own Killzone 2 and Killzone 3 and want to play the original Killzone with Trophies and in HD? That’s where Sony’s newest announcement -- Killzone HD – comes into play. Available on the same time as the Trilogy, and only on PlayStation Network, Killzone HD will cost $15 and will be a way for those already familiar with Killzone 2 and 3 to play a reworked version of the original.
