DOOM: The Dark Ages, Playthrough, (No Commentary), pt.20

Final Battle (?). Using a big mech, I defeated a horde of giant demons and a final Leviathan straight out of some Lovecraft story. It took two tries but I finally succeeded. I then had to fight a devil guy infused with power. He wasn't that hard, challenging, but not too complex. Next up is the final chapter, and what I anticipate is the last boss.
