Star Wolves 3 Final Mission *Spoiler*

I don't recall which path but I think I remember this particular ending battle. You can't get rid of the Super Chimeras; any you manage to destroy are replaced (used a godmode cheat to confirm). I don't remember exactly what you have to do though, sorry. Without a save I can't remember what you have to do to finish it. Have you tried running (use a portal to flee)? What exactly does the mission objectives say?
