There are a bunch of bear traps around too. So if you can get him stuck in those you can light him up with throwables or gunfire

I just shot him twice in the head with the 50BMG sniper

Already knew this

I like running around and playing with him for fun

3 stabs with knife and dodge.. 3 stabs and dodge... That's all u need to do

1 shot to the head with the 50 cal

Melee.  Sawblade axe.  Takes most of the durability.   Three whacks duck and roll.   Takes about 20 hits.  No ammo spent.  Later when you get the superior axe it takes 10-12 whacks and you can get 4-5 at a time.  Same with the reacher.  Melee, melee, melee.

Breakers are easy to kill if you just use your melee weapon, hit three times roll away, hit three times roll away, etcetera...

I stealth kill him from the grass at the far end of the area with a vantage of him it the airplane feeding with the crossbow, works every time just takes a little longer. For the first two or three shots I set a mine at the point he stops in front of the red explosive crate.

I didnt know the red box exploded

Me i just use the growler gun drop him quick

I used chicago chopper very easy kill

Without red box i kill him... Preety easy..

If you have the skill, smoke bombs and melee….  Killed easily and in less than 15 seconds.

Stealth kill, if you have the ability?

Fast
