Did you know there are Halo 3 cheats for weapons and other effects? Also listed are skulls and armor tips in both videos and text.

CHEATS AND TIPS:
The following cheats can be performed during a local match or replay only. You must simultaneously press and hold the following buttons for three seconds to toggle the effect on or off.

Keys description:
LB = Left Bumper
RB = Right Bumper
LS = Click in on Left Analog Stick
RS = Click in on Right Alalog Stick

Code effect:
* LB + RB + LS + A + Down [D-Pad] enables: Toggle “Hide Weapon”.
* LB + RB + LS + A + Up [D-Pad] enables: Toggle “Show Coordinates”.
* [Hold LS + RS] Press Left on D-Pad enables: Toggle Pan-Cam / Normal while Show Coordinates is on for different “Camera Modes”.

Getting extra grenades:
* In multiplayer or system link mode, when you kill someone make sure you slash their dead body with the Energy Sword to get more grenades.

How to get infinite Spartan Laser ammo in mission “Halo”:
* Once you meet up with Sergeant Johnson shoot him until he falls down and drops the Spartan Laser. Quickly pick it up, and shoot it at him. Keep shooting him until he kills you. When you respawn, knock him down again, and pick up his laser. He should get back up with another laser on his back. When he does, shoot him down again, and pick up the new gun he drops. This laser should now have unlimited Spartan ammunition, making it easier to destroy the Guilty Spark 343.

Skull collecting to unlock new armor parts:
Before you start collecting skulls, remember that you have to start the stage from the beginning (not from a checkpoint), but once you acquire the skull you’re seeking, you can save and quit at any time without finishing the stage. This will make collecting skulls quicker if you already finished the game before.

SILVER SKULL LOCATIONS:

1. Blind (location Sierra 117): The arms of the player and the motion tracker disappear.
2. Cowbell (location The Ark): Your explosives increase in strength.
3. Grunt Birthday Party (location Crow’s Nest): If you manage to get a headshot on a Grunt, the Grunt will explode.

8. Fog (location Floodgate): When activated, the motion tracker disappears.

10. Mythic (location Halo): When activated, all enemies will have twice as much health.
11. Thunderstorm (location The Covenant): When activated, enemies will be of a higher rank.
12. Tilt (location Cortana): When activated, enemies will become more resilient to your attacks.
