Tibran's Revenge!

This is a story of the destruction of the world. A chance encounter between some adventurous tourists and an ancient and deeply evil race turns a peaceful world into hell on earth. The enemy comes from deep within the planet, and sets about systematic elimination of the world's civilizations. The most sophisticated weaponry that man can deploy has no effect against the power of the beasts from below. However, there is a glimmer of hope. Can man though his creativity find a way to defeat the beasts, or is there another way for humankind to survive the holocaust?
