Push whatever your fire button is and point this thing in the general direction of anything under level 200 and you'll shred it. That easy.
TIPS:
- Hold the fire button while your Warframe reloads. When you start firing, you'll skip most of your spooling and go back to near peak DPS.
- The Arcane doesn't really matter. I like Merciless because you spend less time reloading and more time dealing DPS. Deadhead is also nice to see bigger numbers, and it synergizes nicely with Galvanized Scope.
- Hold your fire key as long as you can - you have no shortage of ammo thanks to [Vigilante Supplies] and you skip the spooling animation as long as you do.
