I think that we really need new campaigns such as these ideas: world domination! The heroes need help defeating villains in this map! Team up with friends and destroy all villains before they spread darkness to disneyworld! ( map is Disney world and can be unlocked at lvl 98).
World heroes war! Help the heroes get back their movies from the creeps! You can only use the heroes that are in that movie, such as: Hercules: Hercules,Meg and hades. Aladdin: Aladdin,jasmine and jafar. ( can be unlocked at lvl 55)
Princess power! Creeps have taken over the world and the princesses are the only ones who can stop them! Use these max lvl princesses that the game gives you and kick some creep butt! Girl power!( can be unlocked after you finish the original campaign chapter 5!)
So these are my ideas for new campaigns! Hope you see this and try to make it! Bye! ( oh and I almost forgot that the people who comment can also come up with idea’s for new campaigns!)
