Atomic Protector

_Atomic Protector_ is a fast-paced arcade title, like Pac-Man but in reverse.
The player (a robot in charge of a uranium deposit invaded by aliens) this
time has to protect already laid down dots on the map instead of picking them
up. The enemies are of two kinds: One will run around the map, picking up all
the dots. If all dots are taken, the game is over. If there are remaining dots
when the time is out, the level is completed and the game progresses to a
faster, more difficult level. In order to protect the dots, the player may
bump into this enemy, sending it the other way, or he may set up a portable
wall to seal off the enemy’s path. The other kind is radioactive, and a
staggering warning tone sounds as it enters the maze. It must be caught before
it contaminates you. Each new level is faster, and more challenges are added.
