Atom

You are a member of the decontamination squad and your mission is to eliminate the radioactive sites, the bombs and the terrorists who are responsible for it all. To do this, you are equipped with an excavator that buries enemies with rocks.
The game works on the same principle as the famous Raptor or the mobile game Space impact.

Up and down arrow keys are used to avoid enemies and spacebar (and later other keys) to fire.
The game has 4 levels, the last one just involves driving a bus at high speed through the city and having to avoid houses. Furthermore, the game has not been completed and probably won't be.
