Scribble Shooter is a retro sh'mup with hand drawn artwork and tons of unlockable items and rewards.
In addition to Scribble Shooter, GAME's launching top-down arcade shooter Savage Cosmos in the Moonbase. Again there plenty of rewards to unlock in this throw-back shooter.
There's a host of other stuff available in Home this week too, including some pretty sweet Frogger outfits. For the full run-down, hit up the PlayStation Blog.
