Demo version: Boneyard: Leave boundary
In Boneyard, on the ship, there is a staircase with two flights that leads from the ground to the ship. This staircase is on the right side when you are looking at the Elite spawn on Invasion. Walk onto the upper flight of stairs and look at the fence keeping you from falling off the ship. Jump to the lower part of the fence and turn to the open area. Jump onto the part of the ship that hangs over the edge. You are now out of the level boundary. If there is only one person on the console, if you look at the indicator of where you are (bulkheads, under the ship, bridge, etc.), it will read out of bounds. This is a great location to pick off the Elites in Invasion with a DMR. Note: You can only walk so far over before you fall off the ship and die.
Demo version: Invasion: Plasma turret air drop
In Invasion game mode, after the first round where the Elites take control of the ship, the Spartans will fall back to the garage where the warthog is located.

Fly a Phantom

Go to delete all of these from the map. Click it, and hover over "Yes". Have the player two go into Armor Lock. While he is in Armor Lock, select "Yes" at the "Delete all of these from map" message.

Invisible elite
Set the campaign to Winter Contingency on legendary difficulty. As soon as you get off the Falcon sprint forward and switch to your pistol for better aiming. You'll notice an invisible elite running away. Try to kill him before he gets to far otherwise he'll just dissappear.

Lone Wolf bonus mission

Master Chief Cameo

At the point when the UNSC shuttle docks at the Pillar of Autumn's landing bay, the camera will move to the right (if you were holding the stick to aim right) and catch a shot of a Spartan in a capsule. Should look familiar, right?
