Twisted Pixel's Kinect Marionette Shooter, The Gunstringer, is hitting store shelves this fall. Originally announced as a summer Live Arcade title, the game will now be a retail title with added development time used to flesh out to content and polish the game 

Featuring both Donkey Kong-esque side scrolling platform gameplay, as well as 3D on-rails shooting segments, the game looks to capture the imagination of Kinect users with Twisted Pixel's trademark style and humor. Players will fight a Gatorjack, for example. The resulting offspring of a puppet alligator and a puppet lumberjack. 

Hopefully with the extra time, Twisted Pixel can really produce something special.

They better add a crap load of content to warrant it as full fledged game. I've been wanting Twisted pixal to release a full retailer game, but I don't thing the Gunstringer is meant to be one. If they do one it should be built from the ground up as a retailer game, not decided later on.
