City Defence

City Defence is a 1-player Missile Command game for the BBC Micro.

The player controls three missile launch pads at the bottom of the screen, and attempts to protect three cities from incoming bombs. The player can launch from the three sites, and can steer the most recently launched missiles left and right, with a maximum of five missiles allowed on the screen at a time. There are a limited number of missiles per round. The goal is to destroy the incoming bombs. If a launch pad is destroyed, it is replaced next level, but cities are not replaced. When all cities are eliminated it's game over.
