Digger Barnes sees our hero coming face to face with the Bjurgits - slimy animals intent on causing havoc, running off humans wherever they can find them - including the factory that is our setting for Digger's adventure. Digger must enter the factory and clear it of its hostile visitors - armed only with a pickaxe, Barnes must trap the nasties in a hole and then cover the hole back in again - yes, our hero is literally burying his opponents alive... A clone of the old arcade game 'Space Panic' basically.
