Bio Factor takes place on Earth in the very distant future. It is the year 12915 but the Earth is going through the Medieval era again. It seems that technology could not be sustained forever.
The world is in danger from an ancient evil formed from the Bio Factors. Your task is to (of course) save the world from this ancient evil. Although it is a very difficult task to accompolish, you can do it with the help of two very willing friends.
