Welcome to the Creatceous. It's 66 million years before the first humans will climb down from the trees. Going back seemed like a good idea. Until those SATI guys messed it all up.
We’ve got gear. We’ve got guns. We’ve even bioengineered a few dinos to our liking. And that’s good, because we’ll need it all to survive. History says there’s an asteroid headed our way, and there’s no one left alive who knows how to get back to the future.
