Panzer Dragoon II Zwei is a shoot ’em up released for the Sega Saturn in 1996, it was the second Panzer Dragoon game released but it is a prequel of the series. It was developed by Team Andromeda, one of Sega’s internal development studios. [Infos from Wikipedia]
In the bonus section of the game, the “pandora’s box”, you can find an interesting beta video that shows gameplay from its own prototype (from the Episode 2 mission, mostly from the easy path, with a couple clips from the hard path.). The beta graphic and the details of the level and the dragon / enemies are differend from the final game and you can notice that the music is completely different as well.
Thanks to Mozgus that has ripped this video from the Panzer Dragoon Zwei disc we can take a good look at the beta / proto and compare it to the final version below!
A Panzer Dragoon Zwei proto (45% complete – Feb 02, 1996) was leaked in 2008 thanks to Hidden Palace and The Will Of The Ancients community, a build that is visually nearly identical to the final. It just has a variety of small differences like font and gui colors, different prologue music, and a lot of minor gameplay adjustments. You can see in the third video below a list of those differences.
Thanks a lot to Mozgus for the contribution!
