This demo shows that things don't always go as planned when I am recording my demos. I am attempting to defeat the Vertigo Research Station (level 20) boss, on ACE difficulty.

Things start out well enough, as I clear the near room of minions. But I must have made too much of a commotion, because the boss awakens and teleports right next to me. He proceeds to plant an Earthshaker in my windshield. The net result is not pretty. :-)
