You travel to different quadrants in space where you get rid off the invading alien force by fending them off in dogifghts - it is Star Raiders for the TRS-80 CoCo.
This is a racquetball-like game that is best described as a 3D variation of Breakout.
You are at the end on a rectangular room. On the other end is a wall made of bricks or blocks. The ball travels down to the wall and knocks out a brick. It then returns to your end where you must use a squarish paddle to send the ball back to the wall. If the ball gets past the paddle, you lose a ball.
In the computer version, you must knock out all the bricks of the wall to advance. Each level has more bricks per wall. You begin with 5 balls. In the console version, you must knock out 57 of the 72 bricks to advance. Each level has 72 bricks but the number of balls will lower in later levels. Level 1 starts with 99 balls.
In Fire Copter, the player controls a helicopter armed with both lasers and water cannons. 1-player and 2-player games are available, with players taking alternative helicopter control. The player scrolls over a 3-dimensional wireframe city, looking for active fires. The player needs to position the copter over the center of the fire to spray water cannons to put out the fire. In addition, fire starting androids are present throughout the city, which need to be shot with the copter's laser cannons. The player receives points for fires put out and androids destroyed. As fire spreads, the city is in critical danger, and the player loses a life when too much of the city is engulfed in flame. The player has a total of 3 lives, and when all are lost it's game over. The fire has been quelled at the start of each life, and the city begins to burn anew.
FlightSim I puts the player inside the cockpit, behind the controls of a high performance jet. This game is in the conception of the Flight Simulator computer game series but for the TRS-80 Color Computer.
The simulation environment consists of approximately 22,185 square miles and recreates most of the conditions normally encountered in actual flight. The player can fly the jet to any of eight airports or nine landmarks scattered throughout the simulation area.
Quasar Commander is an exciting game of skill to play on your TRS-80 color computer. You are at the helm of a Starship. Imagine that your video screen is a window looking into outerspace. Your laser sights are in the center of this "viewscreen". Try to destroy as many enemy ships as possible before colliding with them. This game contains variations for countless hours of fun.
The player takes command of a ship (presumably a graviton) on an x axis plane to collect and shoot electrons at a spinning atom to obtain a new atom. For example, if the player has one electron circling, he or she would shoot another electron in place to make a hydrogen element. If the electron misses the target and hits the nucleus, the atom becomes unstable and blows apart, sending electrons flying around the game screen, and the ship needs to find safety behind barriers located in three of the four corners of the arena.
