Endure and weapon tips

the best tip for getting endure is to go to the map alpha site because of its X style its easy to have 2 on each side of the X bases and have most of the enemys die in the center of the X

- the plasma pistol is good to take down brute shields also its easy to kill engineers with one hit
-your automag is the best weapon for small targets and brutes with no shields DO NOT WASTE YOU AMMO ON SHIELDED BRUTES HUNTERS OR DRONES
-if you want to keep your SMG its good to take down swarms and brutes
-plasma gernades are good againist hunters althought team work is best to take them down
-assassinte chieftans you cannot stick chieftans they will just bounce off
-beam rifles can headshot most brutes and sniper rifles are nearly useless
-there are more weapons that can work but these are the best

Glitches

Back to top

Hijack a Wraith

You need 2 people to complete this glitch.
One person(the person who's not getting in)needs to have a plasma pistol.

Start off by you and your friend taking out the wraith gunner. Then someone stand on top of the wraith(on the cockpit) and take off the cockpit door so you can see the brutes head. the person on the wraith then needs to find a spot on top where it does not say "press RB to board". The other person needs to keep shooting plasma pistol shots at it so it stays down and can't move. the person on top then needs to hit or shoot the driver and hold RB while doing it. If done correctly then the driver should die and you should get in.

*Helpful on firefight and getting Endure, but is kind of hard to master*

Easter eggs

Back to top

30th Audio Log

Requirements:
1. Must have unlocked the other 29 audio logs
2. Must be at the point of the story where you unlock the mission "Data Hive"

Once you have unlocked the other 29 audio logs, start Data Hive and follow the paths until you come to a Marine soldier who will follow you(he's equipped with a shotgun). Keep the soldier alive until the tunnel that has ice on the walls. He will then say something like ,"I have to take care of something, don't follow me". Follow him into the room and the audio log should be on the wall(looks like a telephone). The achievement is yours!

Remember reach

on the first level, if you go down a hall (i don't remember where it is exactly, sorry) there's a dead marine on the floor with a shotgun, but on the wall writen in white paint is "Remember Reach" as a refrence to the next halo 3 game, Halo Reach.

Sandbox/Forge Skull

First go to forge on the map Sandbox. When you start, your going to want to place a sender node. Then fly to the highest point and look towards the sun. The skull is between the pillars to the right of it. What your going to have to do is spawn a receiver node, hold it as far out as you can possibly hold it out. Next, spawn a bubble shield because the towers will shoot at you once you leave the premises surrounding you. Now your going to carry the receiver node in between the pillars. Move fast and accurately. Now you can get the Sandbox skull which is worth 25GamerScore.

**Remember**

Throw your bubble shield as soon as you go through the sender node!!
