Currently under development by indie devs Vertigo Games & Jaywalkers Interactive and scheduled for release sometime in 2015; Arizona Sunshine is a first person Zombie shooter that's being built from the ground up for the soon to be released HTC Vive.
Both Vertigo Games & Jaywalkers Interactive are no strangers to VR with Vertigo Games being responsible for the Oculus Rift enabled World of Diving and Jaywalkers for the Oculus DK1 classic Blue Marble.
Little is currently known about Arizona Sunshine other than it'll take advantage of the Vives Lighthouse tracking system and support "Room-space VR" with "Motion-controlled weapon handling".
"Step into the midst of a zombie apocalypse as if you were really there, and bash, slash and explode your way through hordes of undead close enough to touch. Arizona Sunshine has you battle for survival across a blistering hot, post-apocalyptic Arizona. Brought (back) to life with SteamVR on HTC Vive."
