Halo 2 Enemy Faq Cheats

Enemies

Grunts: The basic enemies. They can be yellow, red, green, black, or heretic. They can use plasma pistols, plasma rifles, plasma turrets, and fuel rod cannons. Use a melee attack to the face twice or back once for an easy kill. Any weapon can easily kill them.

Jackals: Special force assassins. They can have a blue or orange shield. They use plasma pistols and beam rifles. Melee them twice in the face to kill or shoot the black center of shield.

Elites: The infantry of Covenant forces. Can be blue, red, gold, black, white, silver (Arbiter), heretic, or royal. They use plasma rifles, carbines, SMG's, or energy swords. Use a plasma weapon to take down the shield then shoot them in head. Melee them in face about three times.

Wasp: The only flying enemy. They can use plasma rifles. Can be blue or green. Zoom in with a battle rifle and shoot them twice.

Hunter: Protected enemies built like a Scorpion tank. Only blue. They can use the fuel rod cannon. Shoot them in pink spot on back or torso with any weapon. The needler just bounces off their armor. Rockets work the best.

Brute: Resemble evil gorillas. They can be grenadiers, riflemen, or royal. They can use brute shot and brute plasma rifle. Shoot them in head, or throw a plasma grenade on their back.

How to beat Brutes:
The best combination of weapons against a Brute is to use two plasma rifles. Brute plasma rifles are recommended, as they are slightly stronger and shoot faster with a slower heating process.

On the final level, once you reach the door that leads to the final battle, a group of Brutes will come out. Instead of fighting them, use your invisibility gear and sneak through the door without having to fight. REMEMBER: You must be fast or the door will lock.

The Brutes' weakness are their heads. That is why they usually have metal plates. Shoot them in their heads for an easy kill.

How to beat Elites:
When battling with Elites, do not hit them once with your weapon. Always hit them multiple times. If you hit them once, they will have a faster time and kill you with one hit or take down your shield. Additionally, an easier way to kill Elites quickly is to double-wield the SMGs and aim for the head. Be careful, as the SMGs tend to send the reticle upward. Also, try meleeing him before using the double strategy.

You can outsmart Elites in some battles by finding cover and returning fire as usual. However, when they stop firing, relocate to other sources of cover and have a few seconds before they notice. Also throw grenades before they get all the way out, if they are appearing from a door or a ship portal.

Dual wield a plasma pistol or rifle and a Human pistol. Use a plasma pistol or rifle to knock down the shields quickly, and then shoot them in the head with the magnum.

The best way to quickly kill an Elite is to hit them multiple times with your weapon. First. hit them so they are stunned for a few seconds, then shoot them quickly. They should die easily.

How to beat Floods:
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).

How to beat Grunts:
With big groups of enemies, kill off the Grunts first, as they are easier to kill and become less of an annoyance. Additionally, two slashes with the plasma swords are good against Grunts. However, hitting them with the grenade launchers three times can kill just as easily and does not use any ammunition.

Get a needler. Find a grunt and aim close to his head. Shoot him and he will jump in the air and die.

How to beat Prophets:
To kill Prophets, you must dodge there laser attacks and get up close until the message to hold X to board appears. Do so. Once onboard, tap B to attack them. Three hits should kill them. If not, repeat until it falls. 

How to beat Regret:
To easily defeat the prophet Regret, jump on his vehicle then hold X to board it. You can then press B to melee him to death. 

Defeating the Scarab:
When you fight the enemies on the Scarab, mostly Elites and Grunts, start running down the path. You will see rocket launcher ammunition. Collect it if you have a rocket launcher, as it will make battle easier when you enter the Scarab. Your second weapon should be a shotgun or dual plasma rifles in case you lose rocket launcher ammunition. 

At the last part of metropolis were you have to stop the scarab, jump onto it's head and walk into it's neck. From there you should,be able to see the enemy and shoot the enemy, which can't see or shoot you.

How to beat Tartarus:
When playing in co-operative mode under the legendary difficulty setting, get a grenade launcher that is left over from the Brute on the bridge. When Tartarus jumps onto the spinning disks, jump onto the platform with your partner, then jump on the three disks for safety. Let your partner have a carbine rifle on the top level and have him snipe reinforcements when they arrive. Run around the middle circle, waiting for Tartarus to lose his shield from Sarge sniping him. Hit him with your grenade launcher. Hit him three times, then run away and wait.  Also, never hit Tatarus with a melee attack. Never use grenades as Tartarus will just jump. The most important thing is to not allow your partner to die. 

Get two Brute plasma rifles and run away. When his shields are down, throw grenades then shoot him. He should die quickly.

Run around dodging his attacks and grab a sword off one of your dead elite buddies wait till' his shields are down and do a Lunge attack (wait until reticule is red and press Right Trigger) WHEN HIS SHIELDS ARE DOWN. easiest way to kill Tartarus!

REMEMBER: sometimes this works with 2 lunges just wait a second time and do it again

Easy way to kill hunter:
A way to kill a hunter easily is to throw a plasma grenade on hunter front. Then when the grenade blows up they turn around and stay around for a bit. Then take a magnum and shoot then in their orange skin a few times.

Kill A Ghost Rider:
To kill a ghost rider easily all you have to do is shoot the circle in the middle (the engine) of the ghost and the ghost will blow up...magnum is the best choice to do so
User Cheat by Tony.Lai258

Kill a Person on a Warthog:
To kill a person on a warthog in multiplayer first shoot all the wheels and then shoot anywhere on the warthog and it will blow up...magnum and battle rifle are the best choice
