The game also contains a variation of this mutant known as Blue Armsy who has a low chance of appearing. The enemy has a tendency to attack your buildings (and does it very efficiently - he is able to destroy any structure in a few seconds) - when he appears next to your base, better lure him outside and fight him there. A bit of training should enable you to fight him in melee range, but watch out - even if you are able to block an attack, you'll receive some of the damage. The enemy fights with his hands - consider eliminating him from a distance using a firearm. He is a large (much bigger than the player or cannibals) enemy equipped with three pairs of hands, a lot of health points, and powerful attacks - most of the time, two attacks are enough to kill an unarmored player. Armsy was previously known as the Octopus Mutant.
