Did you know that with a badge to PAX Prime, you'll also get admission to Halo Fest? Talk about nailing two birds with one stone! If you have yet to secure your pass though, fret not because we'll be giving away 20 three-day PAX Prime badges via Twitter over the course of this week. To participate, check out the rules, make sure you're following the official Halo Waypoint Twitter account, and then patiently await the details. The patiently part is optimal, by the way. Just fyi.
