Halo 3, Cortana on Legendary. I hated that level alone.
Isn't that the one where you go rescue her in a flood level? I remember that shit, I hated that map, until I found a Needler.
I had sooo many problems with Nightfall.
Did you check back on Nightfall after getting the latest update?
Apparently that shit must have been too easy or something, & now there's a difficulty setting added to Solo & Custom only. Hardcore is the last difficulty; in hardcore mode, the number of aliens, alien damage, meteors & self destruct aliens, have all been increased with down time after completing hives decreased, & Hunters & Scorps are more frequent. That's not all too, the challenges you do per hive on hardcore is the only skill point your given. So if you don't complete the challenge, you don't get any skill points. Explosive rounds have also been nerfed. The blast radius is smaller now & the blast radius doesn't deal as much damage anymore. I'm like "Alrighty then..... As if this fucking map wasn't hard enough!"
I swear, I don't think devs ever test their shit out before releasing anything. Not just that regular testing shit, but I mean that in depth hardcore testing shit. Like you know how I have the handguns relic active, right? & I'm using .44 magnum & Tank class. They just give you what they have & say good luck completing it. Knowing me though, I'm probably still going to be a persistent dumbass & still beat it. I can't seem to ever stop, for some reason. I'm always moving up until I finally have succeeded. If you ever try it, Ish. Let me know how your doing.
