Mutations

**Mutations** are the mutated variants of the Ridden. Through some unknown mechanism of the Devil Worm, a small percentage of the Ridden will undergo a dramatic mutation, eventually turning into one of these Mutations, each with their own unique inhuman abilities. They don't spawn as regularly as the Common Ridden do, but their abilities can easily wipe out a team of thr Cleaners if not dealt with quickly, making them the true teamwork testers of *Back 4 Blood*.

The Mutations have higher intelligence and more abilities than the Common Ridden. They will sometimes bide their time, waiting for Cleaners to reach ambush areas before attacking them. Several Mutations may also hide after attempting to attack a Cleaner.
