Be afraid; the cannibals want meat, and they're not willing to eat each other! Honor among thieves and all that.
Crash landing in this forest is the best, I mean worst, thing that could have happened! Make sure you grab that ax out of the stewardess' chest before jumping out of the back end of this wrecked plane, and prepare your brain for some survival freaking horror!
Build that shelter, campfire, water catcher, containers for recourse hoarding, log cart (a personal favorite) and traps for those dirty cannibals you're sure to run into.
Fish, hunt, trap, and pop open luggage for food and other survival needs!
This is another survival gamer must, and trust me, the cannibals and other mutants bring the horror.
