Dig Dug is a 1-2 player arcade game in which you have to use your shovel to dig your way through the earth. Stopping you from doing this are two monsters, called Pooka and Fygar, who will continually chase you around. The only weapon that you carry is an air pump, which you can use to inflate the monsters to the point where they explode (if you start to inflate them but stop doing so, the monsters will get turned back to their normal selves).
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.
There are several frogs and caterpillars on the screen. The player must strategically bounce the frogs' tongues off of each other in order to reach and eat all caterpillars.
The player must collect all of the gems. Oddly, the level layout and mechanics are similar to Lode Runner, but the gameplay is largely different (and much more basic).
