I don't know what I'm doing wrong, maybe I'm getting hit too much or wasting too much ammo, I'm using the right arm 81G bazooka in combination with the 88LB3, I'll try swapping to an energy weapon on the left arm and see if it works
Update: I guess it really was the expenses of the Bazooka rounds, cause I switched to the OGRE and didn't even manage to kill all the enemies, yet I still got rank S. Time to give the duel 01HP build a try.
