"Killzone HD" is coming as a standalone game to the PlayStation Network on October 23rd.
The high-definition remake of 2004's Killzone for PlayStation 2 features offline versus-AI multiplayer and a single-player campaign with four playable characters to choose from. Audio and graphics have also been smoothed out and ramped up, and players can now dig into a new full set of trophies.
Killzone HD will be available for $14.99 on the PlayStation Network. The series' official website will provide information soon on an upcoming double XP weekend event for the game.
