I conducted a short experiment and confirmed that "melta rifle" and "plasma pistol" can not trigger headshot judgment like in version 6.X of the game

And confirmed that this glitch has nothing to do with the perk "ACUITY".

What cannot be confirmed now is whether "volkite pistol" generates volkite to trigger headshot judgment. In version 6.X of the game, "volkite pistol" can be used to generate volkite to kill Tzaangor, thereby triggering headshot judgment, and with the sniper's perk "squad renewal", Bulwark can quickly restore the "chapter banner"

If the 7.X version of the game will modify this setting, it will be a huge nerf to the sniper's perk "squad renewal".

In versions 5.X and 6.X of the game, I really like to use "melta rifle" with the sniper's perk "squad renewal". I can use "scan" almost uninterruptedly
