NATIVE originally started as a “homebrew” shoot ‘em up project on the Atari Jaguar platform by German developers Duranik. The project was eventually cancelled after the developers had issues working on the Jaguar platform and they were also concerned about the game being too similar as R-Type. This did not stop them from showing interest in taking the game over to the NUON and they created some mock-up videos of what the game would have looked like running on the platform. Unfortunately VM Labs, the developer behind the NUON technology was short-sighted and was not interested in the game, effectively killing it forever.
Note that while the videos below say that they are from the Atari Jaguar version, these are actually the NUON demos Duranik had made.
Thanks to Adam for the contribution!
