The first fights that the player will take part in are the campaign battles. Each campaign level features a plan made by the Skull King, which you must beat in order to progress to the next campaign stage. Every few levels the player well face off against the Skull King himself, and his powerful Titan. The Titan is a super powerful unit with tons of hit points and a powerful area attack. Beating the Skull King will allow the player to upgrade their buildings to the next tier.
Each campaign stage has either a minimum hero level requirement, or a minimum troop level requirement. They will set you against a prebuilt plan, which can feature any number of units, heroes, or squads of any size. Beating a campaign stage can unlock any of the following rewards:
- New Heroes
- New Troops
- New Buildings
- More Turtles
- More PvP maps
