Hello. Could it be due to damage dealt or the final damage from the sides? If there’s a recording of this, I could pass it along to the team for review.

What is a good way to share video recordings, other than youtube?

Google drive works too.

I found a decent site for privacy-conscious people. Here's a snippet of a custom match I set up to try and replicate the problem - https://anonmp4.art/v/OSNo2sTuLRAucQl . The first three kills are all back kills. Even if you discount the 2nd one as maybe being a slightly angled kill, I should have gotten a "2 kills from behind" award for the other two, but didn't. 

I hope I don't get banned for that link :-).

I too have much greater difficulty getting kills from behind than I would expect, including when I use Surge to stun and get behind folks.

Any tutorial or tips would be great.

I and others can give you some tips. This topic is specific to tailsting though, and a possible bug, so please start a new topic and we can have a more generalized discussion there.

Alright. I would share the clip with the team.

I mentioned it before but actually the topic creator was one to ignore it and smooth it into me being wrong not a bug.

Im 10000000% sure there is a bug with how ASSAULT weapons from behind counts or not.. I use seeker to do kills from behind and im 100% sure now that i do kill people from behind because they didnt even have time to turn or they ware dazed/frozen. I had a game where i done at least 5 and only 1-2 counted when it was super clear crystal clear i did it. 

I think the issue is with something like where the bullet lands idk.. if i use rocket weapon and bullet lands behind enemy its a kill from behind even if i face enemy eye to eye.

Must be something developers missed with regards to bullet hit spots to your actual position or something. Killing from behind with assault weapons is the hardest thing to do in this game purely because 90% dont count

Yeah it takes me hours of playing over many days to fail to get to 10 kills from behind with assault weapons and a single playthrough to get nine kills from behind easily with close combat weapons. I'm using the same technique in both cases... (Surge)
