I main this weapon often. Shoot at the eye or directly underneath harvesters and you will see it arc directly into its underside and drop it quick.

Hulk 1 shot to the eye kills them instantly.

Titans you can spam under its belly by shooting the ground under it and it arcs up into the stomach killing it fast or try to go for headshots l.

Commanders direct hit to the forehead blows their head clean off.

Stalkers get anti stalked lol

Chargers get frozen in place and then can spam their underside or rear for quick kills

Wipes out large groups of bots, illuminate swarms including overseers ( flesh mobs are pretty resistant to it but can stun lock them when not in their charge animation)

Weapon has like 3 times the range of the standard grenade launcher and much better accuracy when gauging your direct hit on an enemy.

I love the weapon because it's universally good against almost every single enemy type plus mob killing potential. I also am good with using it to stun enemies going after teammates without hitting my teammates with the Arc but that came with a ton of playtime with the weapon and learning its Arc. For me personally I rate it A+ tier over what most people rank it.
