Mutants are the strongest next to Alpha mutants. they can run faster than your car and may attempt to grab either your driver or gunner out of the vehicle. their limbs can still be shoot off but be warned, once you shoot off I think one of their limbs, you have to kill it to get rid of it because it uses its arms to push off your car. (also really creepy looking) they have no skin because it is said that they eat their own skin in a frenzy and can wipe out entire checkpoints in minutes. Alpha mutants are almost the same. Alpha mutants will travel in packs with other normal mutants. alphas will also start punching your car causing shaking to your aim. note that there will never be more that one alpha at a time, and if one glitches, only normal mutants will appear.
