I played for about an hour yesturday and backed out and now i have to start all over. Obviously i was messing around with the controler and stuff, so i only did the first couple of missions. I looked for a save option before i backed out and couldnt find one, so i figured it auto saved. but it didnt
Yes, plenty of places to save, but if your character dies he will be gone for good, even if you load from a save, you will start with a new survivor. Therefore your character has only one life. All characters have different habiilities, like some can run faster/for longer than others. Try to survive with only one character as they get upgraded habilities, like better weapon handling and such.
