343iBot Posted August 10, 2012 Report Share Posted August 10, 2012 Whether you have already caught the disease or you are delightfully itch-free, you'll want to hop into Grifball this weekend because starting today and ending on Sunday, games played and completed within that playlist will present you with the chance to receive a 32,000-credit bonus. Happy Super Jackpot Weekend! Link to comment Share on other sites More sharing options...
