Defeating Floods : FPS / MMORPG / RTS Discussion

Get a Plasma Sword from a dead Covenant Elite and get close enough to the Flood for the half-circle surrounding the crosshairs to turn red before attacking. You will lunge forward and kill the enemy instantly, sometimes killing two or even three if they are in close-enough proximity to the target. This attack only uses between two to five ammo points, so it can be repeated at least twenty times. Note: Do not use this trick on either the small spider-like Flood or the large bulbous Flood, as the explosion that follows will damage your shields.


To kill the Flood, easily use the sword. It cuts right through the Flood in one shot, unlike any type of plasma gun.


To make fighting Flood easier, use a shotgun and an energy sword. The Flood levels are mostly close quarters -- shoot them in the face with a shotgun. This will take down even a shielded Flood in one hit. Then, use an energy sword to vaporize the bodies so that they cannot get back up. The best part is that it will not use any energy sword power.


You can actually kill the human and elite Floods with one shot of the Covenant carbine. Aim directly at the stomach for the human-type Floods (with no long tentacles in their left arm); and aim high in the middle where the head would usually be for the Elite-type floods (with the long tentacles).


Good weapons to kill Floods include the shotgun, energy sword, and dual SMGs.


Run up to the Flood and back off very fast. It will fall toward you and explode, without you having to use a weapon. Note: If you do not get away fast enough the explosion will damage you.

Whenever you have an energy sword and are facing the Flood, it will do the same damage if it is depleted.


It is possible to kill the Flood with the Covenant sniper rifle. For it to work, your parasite victim must remain absolutely still. Aim for his big arm until the crosshairs turn into a brighter color. This is his weak spot. It requires about two or three shots on that mark to kill it. Note: This move will not work on the slow and exploding Flood.
