The BowBlade is designed to look and feel like a traditional bow and arrow with one caveat - there's an iPhone attached. The iPhone goes at the front of the device, the bow is extended, and a trigger at the back fires a shot. When the trigger is fired, a stylus tip touches the screen.
BowBlade works with 35 different apps, including titles like Star Battalion, Final Space, Real Shooter, and Nerf Blaster Challenge.
Various games incorporate extra features like the iPhone's camera and augmented reality to create real world targets, or the iPhone's gyroscope and accelerometer for aiming and firing. Our sister site TouchArcade has a video of the BowBlade in action:
