Remember shooting ducks with the NES Zapper? HTC today announced preorder availability of several Vive Tracker bundles, one of which comes with a similar looking Hyper Blaster to relive (or experience for the first time) Duck Hunt-style gameplay in VR.

The Vive Tracker is a motion accessory designed to bring real-world peripherals into the virtual world for a more immersive experience. It costs $99 by itself and works with dozens of games, but is also being packaged in bundles with different accessories. One of those is a replica of the old-school NES light gun, called the Hyper Blaster.
