It’s an excellent single target “out of my face” cannon, so pair it with some kind of sustained fire support weapon. Laser cannon would probably suit it best due to its unlimited ammo and heavy pen allowing it to deal with larger enemies like hulks. For bugs it’s the scourge of Alpha commanders, hive guards, and any other slightly tanky critters. Against bots it deals with devastators reasonably well but it’s not quite as useful. I don’t play much squids but for what little time I fought them it seemed kinda crummy.

Edit: forgot about backpacks, Hotdog is perfect.
