Crowd control (CC) is the term used to describe an ability or spell that temporarily reduces a unit's ability to fight. The term 'crowd control' comes from the ability to control the enemy team during fights, by either restricting their contribution or means to escape. Crowd control is also often split into two types: "soft" crowd control, which hinders a target without specifically preventing them from performing any action, and "hard" crowd control, which negates or blocks the use of certain effects. There are many different forms of crowd control in 300 Heroes, each of which is unique in the way it affects its target, as well as the way it can be resisted, mitigated or removed.
