As to whether it found them hidden in a PC folder somewhere, or it's just clearing out the last few bits of its advertising campaign, we're uncertain: but either way Sony has just released these big pieces of artwork for its recent FPS Killzone 3.
Given there's some who like to collect nice pieces of gaming artwork for private collections or to get them printed on a canvas for hanging, we've stuck the four free of any watermark for your downloading pleasure below. They've had to be slimmed down some to fit on our servers - but are surely still big enough for any Killzone 3 fans out there.
Enjoy.
