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!
It was fun for a while, but, I don't know. It's old school. Not saying that's bad, but the demographic they're aiming for doesn't play split screen as much. That and there's like 5 days until release, I doubt that they'll change it. Yeah, you could do a patch afterwards, but again, I doubt it will happen.
