Tunnels

(Read the entire summary before you actually read.)
In the distant future, after a catastrophe uncomparable to any other, the world is left in chaos. Radiation pools, nuclear winter, mutated abominations walking the Earth in place of human and nature, with the only living group of survivors present residing in underground structures like subways and shelters. Harsh, uncaring, unforgiving and smothering, it seems impossible that these people, a testament to what was life, could thrive on this planet. But they haven't been snuffed out yet, and they don't plan on leaving the world quietly.

Rated R for future chapters and violence. Don't expect very quick releases; I'm taking my time with this.
