Defense Penetrator

Defense Penetrator is a 1-player side-scrolling arcade game for the TRS-80.

The player controls a small spaceship that can move in all directions, fire directly forwards, but also drop bombs. The player contends with a number of adversaries, including gun turrets, missiles, enemy ships, and meteors. The player must avoid striking the ground. There is a limited fuel supply, which the player can replenish by bombing fuel silos along the ground. There are 4 progressively more difficult zones. The player has 3 spaceships, and when all are lost, it's game over.
