Quasar Commander

Quasar Commander is one of the original nine cartridges that Radio Shack made for the Coco, and has the honor of being the first 3D game done for the computer. Featuring several different enemy ships (which all resemble ships from the Star Wars movies), it also featured radar views and other things. This game was the best 3-D space shoot-em-up on the Coco until Project Nebula came out two years later. It also had several modes of play, as shown on the intro screenshot. It also scaled the ships well; at times, they could more than fill the screen.
