i ran through the same problem.
what i did was try and find an energy sword and 2 plasma rifles that you can dual wield then get fire grenades and spike grenades.(don't use plasma grenades because the flood can rush you while it is on them and could blow you up).
also try to stay under cover from the flood that can climb walls and shoot you from a distance.
so try that and good luck.

hard fite, i used an energy sword, while my friend used dual plasmas, save ur spike grenades on that lvl until u get to her, and dont use plasmas lol
if u think that is hard??? try that level on Mystic (dif after legendary, get skullz to unlock) she is badass on mystic, that's where me and my friend arestuck
