According to Guerrilla Games QA Manager Seb Downie, one of the most graphics laden PS3 exclusives to date, Killzone 2, will not require any pre-installation.
With many beautiful games like Fallout 3 and Metal Gear Solid 4 requiring hefty 5GB installs, it comes as a surprise that Killzone 2 won't require at least some kind of hard drive installation.
"No install. Optional or otherwise," wrote Downie on the Official PlayStation Forums.
So there you have it. No need to worry about uninstalling other games so that you can fit Killzone 2 on your hard drive. Killzone 2 is expected to release sometime in February of next year. Stay tuned for more information.
