Da Vinci Code Towers

The Da Vinci Code Towers are secret towers located on the Halo 3 Campaign level The Covenant. They appear after doing a variation of the Time Travel Glitch. They are, of course, towers made of Da Vinci Code.

Tutorial
To see these towers, first load up The Covenant from mission start with at least 2 people. Do the forward Time Travel Glitch. Have one person stay back while one other triggers the portal. The one who triggered the portal should commit suicide, and then, walk behind the first tower (not too far though, or else you might trigger the portal back). Keep walking towards the third tower. If you get stuck, slowly walk to the left until you can move. Once you reach the snow by the third tower, have one person stay put. The other person should walk over and touch the third tower, and then jump off the edge. If done right, they should hit a loading point, and survive the fall. If this happened, have the person who triggered the loading point commit suicide. Now, walk off of the snow and you will see two towers that are made of Da Vinci Code. Even if you Time Travel back, they will still be there.
