With the gameplay demo out, here are all the story and gameplay details so far.
Story: takes place 28 may 2560, 167 days after we lost. So about a year and a half after halo 5, obviously a lot has happened between halo 5 and halo infinite. Hopefully it will fill in on some of those details. The banished have control of the halo ring, most likely zeta halo. There is a new villain, brute war chief Escharum. The banished are allied with “the harbinger”, most likely Cortana. The infinity has presumably been destroyed. Flying grunts? Brutes! Hopefully the flood will return at some point.
Gameplay: similar gameplay to halo 5, seemingly without spartan charge, and the new grappling hook. I’m excited to see how it plays out. Definitely has open world elements to it.
