Hey kids, just a quick reminder that a special Grifball playlist is now available on Halo 3. What's so special about it, you ask? Well, for one, winning teams will be awarded double XP, making their ascent through the Halo ranks (and their Spartan Officer achievements) that much easier. Second, the playlist is considered a tournament playlist, and appropriate prizes will be given to appropriate players. We're not exactly sure how said players will be chosen, but we're talking about free prizes, so you may want to check it out, right? The playlist will be active until Monday at noon Pacific, so hurry up, log on, and start earning that precious XP. Don't know what Grifball is? Get yourself learned.
