Four Banshees on The Package

qUOHV6y4KXo& The Four Banshees easter egg is an easter egg in Halo: Reach. It allows you to fly four Banshees in The Package.

Walkthrough
To perform it, at least two players must be playing. They will have to push the box under the Shade turret away, as shown in the video. Player B will then wait behind under the Shade. While Player A must go further and destroy the Deployable lookout tower next to the Scorpion Tank. Once destroyed, Player A must go behind the tower and look (in the Out of Bounds zone) for a button and press it. A second button will appear under the Shade turret and Player B must press it. If Player B fails to press the button after a short period of time, it will disappear and Player A must press the first button again. When the two buttons are pressed, four Banshees will spawn on the roof on the first building.

After this glitch is activated, the Anti-air guns in the next area will become invulnerable and the player will be unable to progress any further. However, if the player destroys the anti-air guns and then does the easter egg, they will still be able to progress through the level with the Banshee. They can take the Banshee inside the area where the two hunters were fought in ONI:Sword Base, but must abandon them there if they wish to continue the mission.
