Been after Suros for a while and was doing a run of strikes. I was on the Mars strike and for some reason the other 2 guys left at the boss so I thought I'd just solo him, literally as I'm putting the final round into him another player joins has no kills not even an assist he gets Suros I get blue engram. I was a tad annoyed and gave up playing for the day. Still trying to get me a damn Suros though
