Based off the story of Dino Crisis...

When the Time Distortion Rift expanded, encompassing the globe, civilization as we know it came crumbling down. It was the end of days... but not the way we had always imagined. No pandemic... no natural catastrophes... and no zombie outbreak. Beasts from another time... a time from prehistory, came into the world, and ran rampant hunting and preying on humanity.

What is left of the human race struggles for survival in the ruins of their former cities, fighting amongst themselves, and fighting off the hungering predators just beyond their stronghold walls.

The year is 2145. The cities once famed and easily recognized are but a fragment of humanity's past... The T.D.R brought with it the climate of the ancient world, melting the polar ice caps, and bringing lush jungle to what was desert or frozen wasteland. The continents themselves have changed with this transition, and cities like New York are submerged in hundreds of feet of water. Much of the Great Plains are at the floor of an Inland Sea.

The large cities are all but abandoned, having become the home of the prehistoric predators that have come to rule the world again, and the survivors have taken refuge on the coast of the Inland Sea in a region that was formerly unsettled between Arizona and Nevada. What was once vast stretches of desert too inhospitable for human habitation is now dotted with the outposts and strongholds established by survivors.

This is where your story... begins... and where it may very well end, in the most brutal ways...
