Retrograde

Retrograde is a video game in the action genre developed by Apex Computer Productions and published by Thalamus Ltd originally released in 1989. It is currently playable on Commodore 64.

You are from the planet Choom, in the Thwok solar system, which is threatened by a group of seven crazed dictators and their intergalactic war. Can you fight them all in this fusion of side-scrolling shooting and top-down combat?

First you fly around the planet's surface and atmosphere, using a jetpack, shooting enemies as they fly around you and avoiding contact with them. You'll have to find planet hunters to access bunkers containing nerve centers.

Unfortunately, they're useless until they're loaded into one of the game's many stores, which is where the strategy element comes in. Shot enemies release credits, which can be spent on 12 powerful upgradeable weapons if you have any to spare. These weapons can be sold to raise funds to upgrade weapons and load them.

Inside the bunker you will have to make do without these weapons, fighting your way to the nerve centers. Fortunately, your Powerfist can be upgraded at the aforementioned stores. Before you reach the next planet, you must kill a boss within a time limit. This takes place in a 3rd person view, fortunately with a full complement of weapons.

It is possible that we have multiple downloads available when different versions exist.
