Aliens+

Aliens+ is a 1-player arcade game for the Dragon 32/64.

The player controls a small vessel at the bottom of the screen that moves horizontally and fires vertically. Enemy ships move laterally across the top of the screen, move down a small distance, and then reverse direction. Four bases offer protection from incoming enemy fire.

When the enemy vessels are almost destroyed, an alien mothership appears to fire randomly across the screen. When all alien ships are destroyed, the player moves to a faster moving level. The player starts with three ships, and it's game over when all are lost.
