For everyone at Amsterdam's Guerilla Games, the hardest part about developing Sony Playstation 3 shooter Killzone 2 wasn't meeting some impossibly short production cycle big companies usually impose on sequels - it was the exact opposite. With Sony Computer Entertainment Europe reluctant to rush the follow-up to 2004's Playstation 2 title about a future interplanetary conflict between warring human factions develop, Guerilla spent the next four years building on the world they envisioned and utilizing the beefed-up processors and Blu-ray fuelled PS3 to execute that vision. After such a long time tweaking and improving and tweaking again, it's not surprising the development team found it hard to let go.
"That's a very difficult thing, especially for all the creatives here," says Steve Ter Heide, senior producer for Killzone 2 and Guerilla co-founder. "They're never completely satisfied or done with it."
