Jackals go scatter to nades like it was a same sided magnet. Do that, then they arent packed together anymore and you can pick them off one by one. and get close, they run when you get close....
yeah the flood are anoying but i found that they are easy to kill witch a number of weapons like th assault rifle in halo 3 and many other burst weapons.
Dude forget the Flood, The fricken grunts are horrible. Sure they are easy pickins, but when you are scoped in on that darn Brute that won't die, those little B*****ds will throw a gazillion stickies on you!
new remedy to grunts, get the Grunt B-day party skull, then it is soooo fun killing grunts! *headshot explodes grunts face into confetti, while group of small children say "YAY!"* so fun......
Pure forms in Halo 3, those damn guys wont go down easy. Most Flood just try and overwhelm you but can be taken down by a shotgun, sword, or a number of weapons...but the Pure forms can take several shotgun shells and they can change into diffrent forms like those porkupine things that can shoot you across the room when you're armed for close combat. That and there's so many of them all together so your ammo just gets sucked dry becase only a few Flood forms actualy carry weapons.
Energy swords and flame weapons are one hit KOs on the Pures. Just so you know. And if you didnt know this, on the level "Cortana" where there is about 2 million flood between you and her, if you go to the dropship on your way there, there is a flamer sitting there, and all it takes is a puff of flame and even tank forms will go down in an instant. however, the carrier forms are another story. Though they will go down easy by the flamer, their bodies explode, extinguishing the flames, so the continuous effect of the flamer doesnt work there, so you have to blast them longer for the flames to take effect.
Just remember the combat forms aren't as vulnerable to flamers as the Pures. Take a shotty to those suckers.
Again, see above post, flamer or energy sword will one hit the Tank even on legendary, though I dont know about on Mythic... (Legendary, but they have 2x health)
Cheiftans, kinda annoying, especially if they get you bogged down with a hammer. Best tactic: get close, but stay to one side of them. Most people tell you to snipe them, but why waste like 2 clips of Carbine/BattleRifle ammo on his head when you can jump in, sidestep, shotgun blast his side, sidestep again, bash once, sidestep again, assassinate? Note, only works like 50% of the time on Legendary, they get alot quicker on Legendary.....
The Flood and Hunters. The Flood becuase they're just plain annoying. Hunters becuase I always take a long time when I try to kill them and I end up wasting time on them. It's just aggravating.
