Lol, I just arrived at the metro on Stella, ahead of me were 2 guys who I'd seen earlier running about, they stood by each other as the train arrived, I was still a distance away. Soon as the train arrived, one guy shoots the other guy in the back and kills him. From where I was sat hiding, I could hear the guy on the chat saying "why? Why'd you do that? We could extract together..why? Why? WHY?". Guy 2 finishes him off. He moves in to loot, so I kill him from my hidey hole.
Soon as I kill him, another guy arrives, must have seen me killing this guy, assumes I am hostile and shoots me in the back, so I have to turn round and kill him too.
Between the 3 dead bodies I got some nice loot, all without being the bad guy in any of the fighting
