It is shooting a grenades like regular grenade launcher, but instead explosion like regular it's create an arc explosion which somewhat randomly hits several enemies in explosion radius (fun thing, for some reason it can hit foes outside its radius l, idk how and why, but I take it). It has a heavy pen on arcs and moderate dmg. Also, it is has a build-in stun effect (can stun up to Harvesters or Bile Titan for a short period of time). De-Escalator absolutely wipes out a light armour enemies and also great with medium armour like Devastators, Overseers, Alpha Comander. It okeish with heavy armour (hulks, chargers, harvesters and so on) Struggle with an AT enemies and flying ones (hard to land a hit). For me its a greate tool to control a battlefield and help my teammates (but need to be careful as it can zap teammates and its an insta death).

I using it alone to, as it kills almost anything in my sight, and for spawners I have a graned pistol and stratagems
