It's hard not to post about these minute details that are popping up about Killzone for the PS3.
A couple of weeks ago killzoneunit.com learned of Guerrilla Games at the Develop Conference, this week thanks Epix at PS3Forums, killzoneunit.com learned that Second Intention has worked with Guerrilla Games on "graphics technology research".
Although they've completed their contract in 2005, they have continued working with Guerrilla Games on what we assume to be the lighting system for Killzone on the PS3.
