Nah, this is the best way, it's how I always do it.
At the very beginning of the fight, where no one has yet jumped to the main platform, kill all the brutes and pick up the shotgun. One of the brutes guarding Tartarus always drops a shotgun, or at least 95% of the time.
Use that and a Carbine. You can find one easy enough on the platform.
Wait for Sarge to shoot Tartarus with the beam rifle, lowering his shields. Get close and give him one shotgun blast. Repeat.
When brutes spawn and come at the platform, just ride the center beam up to the top, and pile on the headshots with the carbine. One shot to knock off their helmet, one shot to brain them. When the brutes are dead, find Tartarus, lure him close to Sarge, and keep going. Use the Shotgun ONLY on Tartarus and whatever else on the supporting brutes. You should have plenty of shots.
