If you see this guy then get away ASAP super aggressive and they charge at you from nowhere... If caught off guard then use all resources and do not back down... These guys become easy to kill when you have swords... Some raptors or a tanky tame is recommended to bring it down swiftly before it can do much damage
So back when i was a new ark player i tamed 8 raptors just for defense, later on i spotted an alpha carno walking down the beach towards my base, and not wanting my newly tamed sarco, and trike to die, I did something any normal person with 8 raptors would do. Me and the pack and charged into battle, lets just say i lost all but one, Silver. Shes still alive today and happy, And we did kill the alpha carno.
