This game is a 7.5 single player but multiplayer coop with 4 players at once it's an easy 9.8....I was playing with 3 other people that I've never met we all fought together to secure a tower and fight off hordes of zombies and a boss zombie then as night was approaching 2 of us broke off to go secure a safe house for all of us for the night well the other 2 climbed the tower to finish the mission of lighting some beacon then we all met up at the safe house to regroup before heading out into the night which then at some point we were invaded by a fifth player "a hunter zombie" which we battled until sunrise.....absolutely the best multiplayer experience in any game I've had in a loooooooong long time definitely recommend it!!!!
