I tried to look up the plot of Bore Blasters, because my focus when playing the game is entirely on exploding dirt, but it turns out the Steam store page doesn't bother to explain any kind of plot either. Thus, the purity of Bore Blasters. Some facts can be divined from the earth, though: you play a dwarf, piloting a small ship akin to Robotnik's flying hedghog killer, and are dropped off on a small, discrete, gem-bearing chunk of dirt. This you pulverise, in a downward direction, with the aim of finding a huge chest of gems at the bottom somewhere. Your drill is the machine gun on your ship, your efforts governed by about two minutes worth of depleting fuel and a hull that can take three hits total. It's cyberpunk by Gimli.
