I just went 21-0 in a game where I was in the mantis the whole time, but didn’t get a rampage metal and I had 18 vehicle kills. I didn’t have 21 kills, I remember getting the running riot and trying for the rampage but running out of time at 18.
This happens all the time in slayer games too- they have one kill number in game then the postgame the number is off by 2 sometimes even 3 kills. I have noticed it before but this is the first time I actually know for sure how many kills I got as once I got the running riot I was noting how close I was to 20.
I just got the challenge yesterday for 15 kills with an automatic weapon in a game yet post game report showed I only got 13 kills with my storm rifle… I never picked up or used an AR in the game.
Don’t recall a host switch in the game. Host switching breaks kill streaks.
