So Silentium just came out yesterday and there is a code you can get to use on Halo Waypoint with it. This code will unlock XP as well as the video below.

If browsing HaloWaypoint.com you’re going to want to click on the “classified” tab (see below):

From there you will get a screen that gives you a tab to enter a code. Click on that, then enter in the code (to the right of the next pic).

Enjoy the video!

You also get 20,000 XP as well when you enter the code.
