The Flood

Learn about the Flood, a terrifying new enemy in Halo: The Master Chief Collection. Discover their forms, weaknesses, and effective strategies to survive.

Sometime during the middle of the game, you'll encounter a new enemy called the Flood. Most forms of the Flood are rumored to be dead marines from the past. The Flood comes in all different shapes and sizes. Since the Covenant fear these enemies, you can often watch Flood vs. Covenant battles unfold. Be warned, however, that you may get the hell scared out of you the level you first meet the Flood.

Infection Form: Found a lot in 343 Guilty Spark. These are little blobs that run around on the floor in HUGE groups. They can bite onto you and suck up your shields and health, but they are extremely weak. Just take an Assault Rifle and spray all of them with one clip. DO NOT TAKE A PLASMA GRENADE AND STICK ONE ONTO THEM. If you stick one onto them, they'll just run up to you and the grenade will explode right in your face. Other ways of getting rid of them are simple melee attacks or a Shotgun at best. When one explodes, it can set off a reaction, causing several more to blow up, so use this as an advantage. Instead of using a Shotgun, Covenant weapons (except for a Needler, which you should stay away from) work great against these. One shot from a Plasma Pistol/Rifle will make them explode, causing a reaction of other explosions.

Combat Form: Most of these will have claws, and if you're short of ammo, they can just come up to them and swipe you while you reload. Other of these dead marines will be equipped with a weapon, which can be any weapon in this game, except for a Fuel Rod gun or a Sniper Rifle. So if you see one with a Shotgun, kill it and pick it up. They may have a few grenades on them as well. Again, the Assault Rifle and Shotgun are the best to take any flood form out.

Carrier Form: The most annoying enemy in this whole game. They walk on two legs and their face is nothing but a fat stomach. If they get near you, they'll drop down to the ground and explode. This can most likely kill you and it gets really annoying. The best way to get rid of this is to have a different explosion kill you or take a Shotgun and shoot them FAR away, because once you do, they'll explode without them touching you. Once they explode, they'll release a few Infection Forms, but it's only about 4 or 5.
