Double your Halo 3 EXP with Grifball

For the duration of the weekend, Halo 3 gamers will be able to double their EXP with a fresh, new Grifball Double EXP playlist. Really, what's better then Grifball and twice the EXP per win? Well, maybe triple the EXP or even quadrupole the EXP, but that'd just be overly demanding.

This limited weekend playlist will officially be concluding on Monday, January 12th at 2AM pacific, so begin your hammer and swording activities ASAP. Hit those orange Spartans HARD!
