"It is 2057, and the Earth is in a bad way. Unfortunately, if a solution to the problem of global pollution isn't found within 5 years, Earth will suffer irreversable cell death of all living creatures on the surface. This can't be changed.
However, a possible way around this grim future has been found. A special mineral, Tritanium Oxide, can be processed to emit oxygen and clean water. This mineral is very rare on our earth, but there is a great supply of it on the earth of an alternate universe, named Planet AJ3905.
