In the next game from Twisted Pixel—the developer behind Xbox Live Arcade games like Comic Jumper and Ms. Splosion Man—you control a cowboy skeleton as if it were a marionette. The skeletal hero runs automatically, but you can guide him with one hand and control where and when he fires the big irons on his bony hips with the other. The game is due to hit the Xbox 360 next month and will not only be the studio's first title to make use of Kinect, but will also be Twisted Pixel's first full-on retail release.

Ever since the release of The Maw, Twisted Pixel games have been known for their quirky sense of humor, and The Gunstringer is no different. The marionette theme has been taken to its extreme, and the game looks and feels like a play. There are, of course, strings that hold up the titular gunstringer, but the rest of the world is also made of realistic materials, as if it was an actual set for a stage performance. The trees are made of cardboard and every so often a hand will appear to move a bit of the environment around. At the end of a level an audience applauds you.

"We had this great main character that's a puppet and it didn't make sense to just drop him into a game world that didn't support the stage play aesthetic," director Bill Muehl told Ars. "If we were going to have the puppeteering gestures and the main character was a puppet, we had to go all the way with it. So we concepted our environments and props to look hand-made, we filmed a bunch of green screen arms and hands that we could have interact with the virtual environment, and we convinced a couple hundred extras to come to a day of filming for our introduction, finale, and reaction shots at a historic theater in downtown Austin."

The goofy aesthetic feels like a natural fit for the game, as do the Kinect controls. The Gunstringer plays almost as if it were on rails, letting you direct your character while he runs automatically. This puts the focus on good old-fashioned shooting. You can "paint" your targets with one hand, lining up multiple enemies at once, and then fire by making a shooting motion. In our time spent with the game it felt responsive, though it takes a few minutes to get used to.

Though this feels like a game designed specifically for Kinect, the team at Twisted Pixel had actually been tossing around the idea of creating a marionette game before The Gunstringer had been dreamed up. In fact, the concept behind the game was the result of serendipity, as Twisted Pixel's chief creative office Josh Bear came upon the idea after seeing a painting of an undead cowboy in a restaurant.

"The best part about that story is Josh saw the painting during a pitch meeting with Microsoft and he pitched the idea right then and there," said Muehl.

Creating a game for Kinect wasn't just a good fit for the idea, it also provided a satisfying challenge for the development team who were able to explore a brand new control method. The team also came upon another unexpected challenge during development when it was announced that the game would no longer be coming to XBLA, but instead would be a retail 360 game. Usually the studio splits itself up into two teams so that it can focus on multiple projects at once, but the shift to retail meant that all of Twisted Pixel needed to work on The Gunstringer.

The studio also worried about fan reaction, since the game was initially announced as a downloadable title that would have been much cheaper than the game which will be hitting store shelves in a few weeks. According to Muehl, though, those worries have been alleviated as the team has filled the game up with plenty of extra content.

"Between all the extra content we added to the main game, the Fruit Ninja Kinect pack-in, and the free Wavy Tube Man Chronicles DLC, I feel like we've put together a damn good package for gamers, especially at the $40 price point," he told Ars.

The Gunstringer will be coming to the Xbox 360 on September 13.
