This week's PlayStation Store store update doesn't shy away from a game release like some people did, bringing the mind-bending puzzler echochrome to North American PlayStation 3s and PSPs. It's the main draw this week, with a Dark Sector demo available for those with tightly shut virtual wallets and a taste for first-person throwing. It's low key, but a whole mess of Rock Band tracks, wallpapers and videos await you after the jump.
