on hunters they are easy if u know how like if u have a shotgun(unlikelly in any level with hunters) run up to them and jump out of the way of their hit and unload shells into there orange wormy back will take them out
do that with ANY i mean ANY weapon and they die u can grab a sniper of a BR and unload at their head hoping that the head will sling back far enough for u to get a shot in at their neck and die so yeah hunters no problem and the flood well only time they get annoying for me is when i run out of amo lol
My worst enemy was no doubt the flying insect things with the plasma pistols. If you ever play on legendary those things are impossible to kill! They're so annoying!
alma fom the ninja gaiden universe (XBox)... especially on master ninja, she was a bitch to kill, much less trying to avoid the huge pillars of flying doom (which got easier to avoid once u learn to ROLL STRAIGHT ACROSS THE LVL!!!)... and her second form, forget about it, did it once and left it at that... im just happy i beat master ninja and DIDNT GET ANYTHING FOR IT!!!! no costume, no nothing (at least that i've noticed)...
the flood is annoying but easy, grunts, jackles, and brutes are the main thing you kill, so i see no matter, but when you're on legendary with all the hardest skulls on and a hunter appears...... HOW THE HELL AM I GOING TO CARY THE FIREPOWER TO TAKE THOSE THINGS DOWN!?!?!?!?!?
and i hate those noobs on xbox live who play on their brothers player who is a 3star general and totally screw it up.
