Bio Defence was to be a game based inside the human body and fighting off diseases.
It was being produced by Tymac back in 1985 and was found out about via Home Computing Weekly magazine (26th Feb 1985) when Tymac were apparently showing the game off to the world at the LET 1985 computer show at the Olympia in London.
Sadly nothing more was heard of regarding the game, though a number of conversions were done for the Spectrum by the company in 1986. However, Tymac actually did complete and release the game on the Atari platform:

So just what happened to the C64 version?…. It sounds like Tymac were showing it off, but maybe it was just the Atari version being shown?
A lot more information needed…
Do you know anything about this game?
