Virtual Reality Asteroid Defense 3d game for Android Smart phones, and headsets to provide split screen Virtual Reality controls to shoot at asteroids or navigate over the view.

To install the .apk file after download, locate the file on you cell phone, and you must go to settings and allow installation of "unknown files," then click on the file and it will install.

Update to Virtual Reality play:  install Fulldive VR to your cell phone.  Open the game, and use the box and arrow to open Fulldive VR, which then displays a split VR screen.  When you open the game you view  look or move.  Look is preferable, since the game is in VR mode.  I was able to play the game on my cell phone, with Fulldive VR active.
