You are alone. Except for the zombies! But there are guns and some ammo. You can fight, but there is No Way Out of this city infested with hideous creatures that will chase you to the end!
In this game the goal is to resist and seek an unlikely exit.
But your concerns are not limited only to the ravenous zombies that chase after you, because to stay alive you need to find food and you're hungry, but unlike the enemies that come in droves all food is scarce and hard to find!
