Honestly try it the hard way blow of his kryl shield and fill him with bullets. If u cant, there is a handy glitch. you know the four blocks of cover? get RAAM stuck on the top right block of cover and kill him (get him on the top right block by roady running there and telling Dom to shut the F- up with tthe squad comands, left bumper and B. Oh, and ignore the Troika/Nemacyst completely. throw all four grenades off the wall to land them at RAAM's feet. Completely finish him off by blind firing a weapon over the top and repeatedly tell Dom to shut up. This Glitch SHOULD work on any difficulty. for more explicit instructions go to Ign walkthroughs (by users) and there are multiple ones on to exploit / get this glitch to work
if you want to kill the berzerker you have to go on the one part of the train and wait for the berzerker to get on then run away then press the button to kill him,and if your goin to kill the RAAM you have to dodge all his swings and just keep on shooting him and when ever he comes towards you run away
His name is RAAM, and you have to either shoot hit with the Torgue Bow or throw a grenade at him to scatter his Kryll. Once the Kryll are off shoot him with the Lancer and eventually he'll have no more fight left and die.
