ROX III

ROX III is an iteration of an earlier VIC20 game ROX / ROX II with improved graphics.

In addition to the base game of shooting meteors (Rox) with your defense rockets before they hit the ground or your moon base, you have three "panics" which will destroy any incoming meteors and a mothership will appear every few levels that needs to be disposed of. It's game over if the surface is penetrated or your base is hit.
