I was playing Halo a little bit ago, on Heroic difficulty no less; and as you can probably tell, it is actually HELL to go through. I was on the third mission of Halo one, inside the Covenant ships hangar bay, then the Hunters showed up. I killed one with a plasma grenade and then ran in circles around the other. After tossing a grenade onto that one, I tried to hide in a corner to recharge my shields, assuming I killed it. I then turned around to see the hulking, wormy mass of the Hunter charging towards me like Thomas the Train Engine and then proceeded to scream like an absolute ***** as the Hunter proceeded to literally slap me to death. The last thing I saw before rescanning at the checkpoint was my corpse being stomped on by the Hunter.
