Guys they announced Halo 5 is going to be locally single-player only. Sign this petition to change that here: https://www.change.org/p/microsoft-343-industies-bonnie-ross-kiki-wolfkill-microsoft-studios-add-split-screen-co-op . Be a part of the people that keep Halo the way it's supposed to be!
Or just buy another X1. They'll be at least $300 on black friday.
