Jet Force Gemini

One of Rare's lesser known AAA titles for the Nintendo 64, Jet Force Gemini didn't sell particularly well, only about a million copies and has never had a sequel or even an Xbox Live Arcade remake. It was generally met with very solid reviews, despite being criticized for the somewhat clunky camera and stiff controls. It's also pretty gory for a T-rated game.

Hidden N64 Logo


In the Invasion cutscene (the one that King Jeff shows Juno at the beginning of the game), the Nintendo 64 logo appears right as the ship lands on the tribal. It can't be seen normally because it is hidden inside of the ship.

The logo model itself isn't used anywhere else, not even in the logo sequence.
