Oscar's Lair is the first boss level of the game. It is the last level of the first episode. In this level Nick fights Oscar, one of Dr. Riptide's deadly creations.


  • In the shareware version, after defeating Oscar, Nick's sub sets to "autopilot" and automatically heads to the exit.
  • In the full version, there is no "autopilot", and there is no story text screen after exiting the level.
