Crawl or Die

Set in an indistinct future where Earth has been leeched of most of its resources and a new Earth called Earth 2 is being populated as a replacement. A group of military mercs are sent in to rescue the last fertile and healthy female on the planet and get her past a war zone against what looks to be a grungier version of Giger’s xenomorph. But in order for that to happen, they’ve got to crawl!
