This stage, as the name states, is a pseudo-organic stage in the game. It's full of gun turrets, invincible tentacles (inspired by the tentacles from the first stage of Salamander/Life Force, as those can be destroyed), alien spewing eggs (which may have been inspired by Contra) and destroyable grey barriers. The boss of this stage is Big Eye, who is probably the heart of this big synthetic life form.
