During E3 '98, Fujitsu announced a TEO spinoff called "BioPunX".
It never released and the trademark was abandoned in 2002. Very little evidence of this game exists beyond a few publications.
"The latest product that is intended to appeal more to men is the computer game " BioPunX "."
- Wirtschaftswoche - Volume 52, Issues 46-49 - Page 116 (1998)
"This is a simulation program, featuring four "BioPunX" creatures. Each has a unique personality and attitude. The idea is to train them so they can complete a mission. Not yet reviewed."
- Complete Sourcebook on Children's Software (1999 and 2001)
"...a new generation of games in which artificial creatures save the earth in 3D animation. Anyone who wants to can even communicate with the "Biopunx" using voice recognition."
- DIE WELT: Mehr Glück im Computerspiel (27.08.1998)
In 1999, Fujitsu Interactive went out of business. However, Shigetoshi Akasaki, the president of Fujitsu Interactive, announced that the game was still being worked on in a GameSpot article a year later.
Two years after this announcement, the "BioPunX" trademark was officially abandoned.
In 2013, the rights to "Biopunks" and "Biopunx" were acquired by some German lawyers who have held onto it ever since.
This wasn't really Fin Fin related but I just wanted to talk about this because nobody has compiled info about this game anywhere else.
