Writing on the US PS Blog, product marketing manager TJ Consunji confirmed that the game will be available in the territory from February 22, 2011.
Developed by Guerrilla Games, the title will feature 3D technology and fleshed out multiplayer options. It was showcased at E3 earlier this year, where it bagged multiple awards.
"Guerrilla Games has been hard at work making the most explosive shooter possible on the PlayStation 3 system," Consunji wrote.
"At E3, the development team gave you a glimpse of Killzone 3 in 3D where they walked away with Best Shooter, Best 3D graphics and Best PS3 game to name a few of the E3 awards received."
Killzone 3 will be available exclusively for PlayStation 3.
