So sniper47 is a hacker? This image does not much help about this, also who ever made the screenshot username is TheBestHacker so do you mean them tho there are MSg. in this image (and just could that the username dose on meant there a hacker) also NoxAnima in the Twitter panel is asking to be reported did they meant to say report to me.
I see five players: one dead gunner in red team, one commander or an assassin (with there black skin) or maybe it a gunner ever way its in mid jump/flight, one tank or blazer (where the red laser is) and behind that a tech hackers (or not) spaning there heal AOE (can't see it but can tell where it is witch is left of the tank/ blazer's) also one more player icon can't see what class (it just above tank/blazer's icon). (all the other said are one blue team)
Here is a zoomed in image of the screenshot for you people with bad eyes
Note: I don't know if the commander/gunner/assassin (look like commander to me) has the jetpack on because there being hit with the AOE health giving that red glue (the smaller red glow around the commander is near the red glowing shock waves and bright centre (hacker)) so if there jetpack was on there should be a defter glow/emission of some kind from it's back so it probes just in mid jump.
I did not play in this match so I did not have any other points of vouge apart from the screenshot (it don't help that where the red beam is coming from is a blob of fire and the Capture point maker is in the way, also the blazer could also be a blaster)
