There should be a multiplayer option... I really liked it overall as I liked Rebuild 1, new greater functions though! A trusty dog, is a pug xD... As I enjoy Zombie Games I always play them on the hardest mode, and impossible sure is challenging.... And impossible, I would like to see a Rebuild 3 with some muliplayer perhaps ^^
