Earthfall

Alien invaders swarm the rubble, hunting survivors. Humanity is an endangered species. Want to save the world? Grab a gun and fight back.
The end of the world is here! Emerging from the devastation of a global meteor strike, aliens swarm the landscape and ravage the planet. Everyday people must stand together and fight back with a wide variety of weapons, supplies and defenses as they battle through the towns and wilderness of the Pacific Northwest.
