Brute boss
The best way to defeat tartarus is to get duel brute plasma rifles and switch off on right after another so there is an endless stream of bullets firing at him. And keep shooting him no matter what, especially on Lengendary. You may hear some people say not to shoot him when his shield is up, but thats bull shit!! They still do some damage to him even with his shield up! But they do a shit load of damage with it down!
