A prototype game that was never officially released for the Atari 5200, Frisky Tom is a port of the obscure Nichibutsu coin-op of the same name in which you play a plumber who must climb up and fix broken pipes to keep a steady stream of water flowing from the tank at the top of the screen to the reservoir at the bottom. Unfortunately this house is infested with mice which roam the screen, gnawing through pipes and generally causing problems for our man Tom. Once a mouse gnaws through a pipe, you'll see the flow of water stop and a pipe piece will fall to the ground. To repair the pipe Tom must pick up the fallen piece (you can hold two pieces a time), and put it back into the hole. To get to where the holes are, Tom must carefully climb up and navigate the maze of pipes. Although Tom can cross short gaps in the pipes, he'll need to go around the larger ones. While climbing around on the pipes, Tom will run across several different kinds of mice. Each mouse has its own color and purpose. When the flow of water is i
Tempest is a shooter using wire-frame graphics. Each Wireway is taken on in turn, and has a network of lines guiding the movement paths of both yourself and the aliens. You remain on the outside and keep shooting as the aliens move towards you. Any that reach the outside are fatal to touch, thus limiting your range of movement greatly if 2 or more achieve this. Some aliens move sideways - in dealing with these, plan ahead, allowing for the time your shots to take to travel. Tempest was not officially released for the Atari 5200 platform. But an initial prototype was finished by Tempest's original programmer Keithen Hayenga and released by AtariAge in 2009.
An unfinished prototype game that was originally planned as a shooter but the last available version ends up being more an action/adventure game. There is an early build available of the shooter as well. You are a warrior named Meebzork who can practice or play through 6 different levels (not including another level that was going to be after you completed a board and would allow you to choose a next one). All 6 levels are different in what they require to complete.
This unreleased, unfinished Atari 5200 game is similar to Broderbund's famous game, Karateka. Select your black belt level (difficulty level) and fight your way through eight rooms. The keypad is used to execute a variety of karate moves, although the game has no collision detection so you can't really fight your enemies. While the game looks promising, you cannot progress beyond eight rooms because you can't defeat your enemies.
Astro Chase is a multidirectional shooter written by Fernando Herrera for Atari 8-bit computers. It was published by First Star Software in 1982 as the company's first game.

A port of the classic computer game, A.E. (Which stands for Anti Environmental) is a most unusual 5200 prototype. It was never announced by Atari nor was it mentioned in any internal documents. A.E. is an arcade style shooting game in which you have to shoot down waves of evil flying mechanical stingrays in order to save your planet.
The Atari 5200 version only has four levels as opposed to ten that the computer versions boast. The loading times for the levels are also longer due to hardware constraints of the Atari 5200.
In this game, you guide a marker which must draw rectangles and other weird objects in order to claim your territory, and you can either draw these rectangles fast or slow. Drawing the rectangles using the "slow" method awards you the most points. Once a rectangle has been made, it will be colored in to show that you have claimed your territory. While drawing the rectangles, you need to watch out for Qix (pronounced "kicks"), a series of colored lines that crawl the screen. In addition to Qix, you also need to avoid the Sparks who travel around the border, as well as any lines that you have made, as well as The Fuse, who travels along the line that you are drawing. Once you have claimed enough territory, you proceed to the next level.
