If zombies weren't enough, add outsiders to that mix of danger! The purpose of this game is like different titles in this arrangement. You must complete each level without any of your characters passing. In each level you have to find the exit entrance and to do this you have to collect all the information circles. The game highlights 18 unique levels that you have to complete. These levels are provided at the very beginning except the first. You can open them individually as you play. You can control two characters alone or play the game with your companion, sharing the console as you each control a character. You will have to restart the level if any of your characters pass. Best of luck!
