Underground mod for Serious Sam: The Second Encounter

The creation of a renewable, pollution free, powerful energy
source has been one of science's greatest challenges.
In search of a clean renewable energy source scientists
began to research a sollution to the energy problem.
One possible solution came down from the sky.

Rarely when an astroid hits earth it will carry a strong magnetic field.
It is said to be caused by an unnamed element embedded in the rock.
Even though it is considered the most usefull element known to man, it is
so rare and in such small amounts that it can not be useful in any way.
And if enough of it is found it would be possible to create perpetual energy.

One day a geographer stumbled upon a large chunk of this element
about two miles below the surface of the Mohabe desert.
On June 8th 2003 the Vulcan mining project
was established to extract this element.
The project made constant progress...

...until something went wrong.
