In the olden days, human beings were attacked and devoured by ferocious blobs. But now, in modern times, labyrinths are constructed below ground to safely contain the blobs. Once every quarter, patrol bots are sent down to thin out the herds. But one day, something goes horribly wrong. The blobs have mutated and gotten tougher and more monstrous. All the patrol bots have been destroyed... all but you, that is. You are now the one bot standing between the blobs and civilization. Can you destroy all the blobs and get safely to the exit before you run out of power?
