Crolon Diversion

Crolon Diversion is a 1-player arcade game for the TRS-80.

You have been chosen as an emergency replacement for one of starfleet's better pilots. Your mission is to create a diversion by doing lone battle against the deadly Crolon forces. Hopefully you can last long enough to draw many Crolon fighters away from the main point of attack.

The player controls a damaged craft which continuously moves up and down, and the player can only control its horizontal movements. The player can fire at enemy vessels to try to destroy them. The player takes 5% damage if they hit an enemy vessel, and if they reach 100% damage, they are destroyed. Crolon ships appear on the screen one at a time, and if 6 ships appear on the screen, it's game over. If a commander ship appears, the player has 20 seconds to destroy it, or it's game over. The game or fuel lasts for 999 time units, and after this time, the game is over. The player receives a promotion based upon their final score. There are a total of 5 levels of difficulty, based upon which sector the player chooses to defend.
