As for DH the game, well we got to see the Nerd do John Milius dialogue, and hey if you play the godawful Lethal Enforcers those DH-style shattered-glass bullet-holes are all over THAT, so the Konami gun makes perfect sense. I wish the Nerd would make fun of Lethal Enforcers. And "YOU'RE JUST COLLECTING BAGS OF COCAINE!!!!" was very funny. So was the "mountain" stage where you can't see where you're supposed to jump.
The game's graphics look like a garbage version of Bionic Commando and the NES was on its way out by then. The bullets look like Metal Gear's and I love that that big "gun" boss just keeps firing in a straight line even though you're on a roof.
