There is a thing like that in the game ?

I shot a lvl 3 female out of a pack today and they all scattered. Last weekend i wacked 2 lvl 7, a lvl 5 and 2 females and got killed. I dont think that alpha thing is an actual thing.

I don’t think this is how it works tbf. Sometimes packs disperse simply because I’ve fired in their direction. Other times they’ve refused to end the attack until I’ve shot each and every one of them.

You can do this too, don't give up and good luck!
