Hear me out Treyarch and Call of Duty, if you do add on zombies see if you can work with Warner Bro’s or whoever to add the Mystery Incorporated gang in a Zombie Island Map! Similar to how you introduced call of the dead, have Scooby get taken by the Zombie hoard and the gang survives and completes an Easter egg to free Scooby. It fits within the 60s-80s time period and you already have a dynamic cast of Fred, Daphne, Shaggy and Velma to play as. Maybe make Scrappy Doo be responsible for 935 reaching the island and make him a boss in a robot suit that appears every 6-10 rounds! SUPPORT THIS WILD, RIDICULOUS AND GENIUS IDEA!!!!
