Shawnimals is about to return to video games with the impending release of Ninjatown: Trees of Doom for the iPhone. Created by the Venan Entertainment, the folks behind the Ninjatown DS game, this one brings arcade style action rather than the tower defense game play of the older title. With sweet, bright graphics Trees of Doom should bring the joy of Shawnimals and Ninjatown to an iPhone near you for just $1.99 a pop.
