Science has often wondered: Can the bridge between man and beast be breached?

Warring nations have always sought to create "super soldiers". The cry grew loud in Germany during WWII. Four scientists tackled the possibilities, wanting to take it a step further. How? By breaching the barrier separating man from animals, combine genetic codes in one DNA strand.

Of four undertaking the possibilities, one succeeded. Unfortunately, evidence of his work vanished after the war. Decades later, it resurfaced. This time technology, and science, had caught up with each other.

By 1999, experiments using the flawed research material got underway. Ten years later, trials commenced. The results? Catastrophic, resulting in mutations and madness within the subjects. The more cunning broke out of captivity, going in search of what would sate their appetites, a nightmarish quality of an unthinkable magnitude.

It's when Hell opened up for business.
