Mineshaft is one of the many upcoming fan-created films from Machinima prime. This one in particular was created by Steelhouse Digital and written and directed by James Farr. Like it? Then make sure to check out the excellent Fallout Nuka Break—Red Star, which came before Mineshaft: it's not as fun, but it's just as excellent.
Now excuse me, I think I need to go rewatch Black Dynamite.
