Sony will release a boxed set of all three console Killzone games on October 23 for $40, the company revealed today, saying the first one, which was made for the PlayStation 2, will be getting a 720p upgrade.
This is just the latest in PS3 bundles. Previously, Sony has sold God of War, Ratchet & Clank, Team Ico, Sly Cooper and Jak and Daxter collections, bringing a whole lot of PS2 and even some PSP games to PS3 on disc (and for download). Most of these games are not playable on Sony's current console which dropped back-compatibility support several models ago.
The up-rezzed original Killzone will also be sold as a standalone game, according to the series' official Twitter feed. It will include Trophies.
