Caldera Defense

Caldera Defense is a virtual reality game for the Google Play and Oculus Rift platforms.

Official Summary
VR tower defense where YOU are the tower! Harvest energy from your Caldera on a hostile alien planet as bandits attack with tanks, drones, fighters, and bombers! Shoot cannons and guided missiles at incoming air and ground forces while holding out for help to arrive. Sell refined energy to repair and upgrade your base. Build structures with strong defensive and lethal offensive capabilities. Can you survive the onslaught? Uses Google Cardboard for VR viewing, but can also be played in non VR mode as well.

Designed for Galaxy S5 class phones and above. VR is very resource intensive, thus the game may run very slow on not at all on lesser hardware.
