Another fun-filled Playstation Store update. The big download this week is echochrome. Have you tried the demo yet? It was a bit hard for me, but I’m a dummy. Anyway, there’s also some add-ons for Rock Band and Karaoke Revolution Presents: American Idol Encore, a demo for Dark Sector, a whole bunch of game videos and some new wallpapers. If you want the full details, hit up the “Featured Section” of the Playstation Store or visit the Playstation Blog.
