What would happen if you took all of the games in the series and put them in a blender? The result would be Gradius ReBirth, a fruity twist of all the best parts of Gradius.
Aoba Anoa from the Otomedius series appears in the files for the Vic Viper, vic_viper_red.bmp. There is also a silhouette of her sprites found in vic_viper.bmp. Judging from her amount of sprites, she might have been considered to be a playable character.
She even has a life icon hidden in font.bmp.
The Crawler X is animated with multiple segments in-game, however, an assembled version can be found in stage2 boss.bmp. It could have been used for a reference guide on how it should look, or may have acted more similar to the Crawler found in Nemesis on Game Boy.
The very same graphic has a hurt version where the shell is colored orange along with the eye. In-game, only the eye becomes orange when the boss is hurt.
A rather boring and choppily-made title screen can be found in _title.bmp.
Hidden in \map\stage3_01.bmp is some text presumably by one of the artists.
