I didn't make it!
So I want to do some arena fights, but for some reason Arnie is an enemy towards me. I never even did anything to him. Is there any way that I can reset him and make him neutral toward me again? Or is it impossible?
You will be enemy to individual stalkers if you kill any of their friends and they see it. And you are stuck with that. (Btw "my" Arnie was killed by some soldier that infiltrated Rostok. That guy do not live a very safe life...)
