okay Cortana was the annoyingest level of the whole campagne,i had to do it with 2 other friends

i found siera 117 and crow's nest one of the hardest level to do on legendary but halo was easy on legendary

Depends on the difficulty setting, but Cortana is really annoying. I mean, trudging through disgusting areas where the walls are made of Flood infection forms that reanimate all the guys you kill and then having to run back through the entire level is ridiculous.

And those Flood forms that shoot the projectiles are incredibly annoying.

on legendary it would be "halo" not the driving part, but the beginning part, with all the flood, its hard in solo, and the scariest, well cortana, but the flood are weaker in cortona than in halo
