YMMV / MDK

• Angst? What Angst?: Subverted. Kurt's manual bio mentions that he's got some reservations about what he has to do to repel the invasion, but this doesn't come up in-game until the ending, where he's screaming in uncharacteristic rage as he guns down enemies; the final shot, after he's made it back to the Jim Dandy, strongly suggests that he's been traumatized by what he endured.
• Awesome Music: The game has some bombastic orchestral/rock scores handled by Tommy Tallarico and Todd Dennis, the most memorable among them that got used for future titles like Wild 9 includes "Facing The Inevitable", "Grenich Time", and "Vengeful Alien".
• Big-Lipped Alligator Moment: Surely there must be a reason that the Gainax Ending in question is a French musician performing a cover of a song that protests the Vietnam war.
• Fan Nickname: The Grunts have been referred to as "Poopsies" by the fans.
• Harsher in Hindsight: In Mission: Laguna Beach, you have to save Laguna Beach from aliens. No, thanks. Thankfully, it's only a short promo disc, and not part of the main game. However, ...uhhhhh.
• Hilarious in Hindsight: Then again, you could let the aliens plow Laguna Beach instead.
• Nightmare Fuel:
  • Some levels are genuinely disturbing, but Level 3 takes the cake here.
  • Grunts, robots... enemies in general.
  • Any time you have to face the tanks.
• Porting Disaster: Some releases, such as the Playstation and Steam versions, removed the Gainax Ending. The PS1 version also has some framerate issues, but is otherwise quite playable. However, it's pretty obvious the game was not made with a gamepad in mind, but the controls work well enough that you can get used to it regardless.
  • Thankfully a fan patch for the Steam version exists which adds in all the fixes of the GOG release, including re-adding the Gainax Ending.
• Sequel Displacement: MDK2 is more well-known than the first game, mostly since the sequel had a WiiWare port and an HD makeover, while this game got neither (though you can still get this off GOG and Steam if you're interested).
