I would recommend this weapon for really any content in the game, due it it having high damage, being kind of AOE, and having reasonable ammo reserves. With this build, you will get quite a lot of headshots, but its innate 1x headshot multiplier makes those worthless. With Primary Deadhead, we get a passive +30% to our headshot multiplier, plus additional damage on headshot kills. The [Tenet Arca Plasmor] has such a huge hitbox that headshots are practically free. With [Laser Sight], Deadhead, and [Galvanized Chamber], your damage ramps up really quickly.
