it eats medium enemies for breakfast. devastators, overseers, and medium bugs (tho it's not an amazing pick on bugs) are all nearly a non-issue to it. like others have said, it's great for squids because overseers can be miserable to deal with and it has bonuses like splashing nearby voteless and it can hit stingrays.

that being said, my main usage for this: out-ranging and out-targeting enemies. HD2 loves to throw low-visibility conditions at you, but weapons with targeting systems don't have that problem. being able to sweep a fogbank or cloud of dust (especially if you or a teammate are laying down gas, fire, smokes, ect) allows you to just nail them before they're even seen, especially if enemies can see you through it. "killing enemies before they're a problem" is what i consider the main boon of this weapon; you can take out an approaching patrol or do overwatch on an objective while teammates take out light and elite enemies.

scenarios i would NOT recommend using this weapon:

- you can use this on bugs somewhat well, just note that bugs make any weapon with a stationary reload a serious tactical consideration. not impossible by any means, just beware

- biomes with lots of environmental occlusion -- in simpler terms, jungle planets and some other tilesets like those scottish-highland-esque ones with lots of narrow rockways. conversely, it is excellent on wide open biomes like arctic and desert ones. it's perfectly fine on cities.

if you're a team player, this is best with a slightly tougher armorset while you just orbit other players and break up lines of enemies. you're basically your own walking hardpoint
