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!
I hope to see that as a DLC, split screen is outdated even though i love it. Halo 5 was really focused on campaign and multiplayer with smooth gameplay (stable 60 fps). I prefer that than the splitscreen.
