Loadout Guide
Primary
Mods are chosen to max AOE and AOE damage. Fear is also chosen for additional CC, but T5C could also be a good choice.
Secondary
Use BRT-7 to slow enemies. I think 1B could be a good choice here, but the additional damage from blowthrough is more fun, in my opinion.
Equipment
Leadburster is chosen for room clearing.
