It's another Thursday and that means another obligatory update for the PlayStation Store. Today's update highlights one of Sony's more unique titles released - Echochrome (PS3, PSP).

Gamers in the PAL regions can now break their brains on Sony Computer Entertainment, Inc.'s (SCEI) isometric puzzler. Both the PlayStation 3 and the PlayStation Portable get their own respective Echochrome titles, each offering players a good deal of 3D levels to sort out.

Let's not forget the other freebies that go along with the weekly update. The demo version of 2K Sports' Top Spin 3 is also available on the PS3, along with several free videos and trailers to spice up this week's release.
