The basis of Halo Wars 2 is separated into two factions, the UNSC and the Banished.
Each faction has separate core units that, while comparable to each other, offer very different styles of play.
The UNSC units tend to be a bit sturdier, while the real strength of the Banished is numbers. While all Banished infantry appear in squads, the only UNSC units to appear in squads are the Marines, ODSTs, and Hellbringers.
After nearly 30 years in cryosleep, the Spirit of Fire’s crew woke to find themselves cut off from the UNSC, facing an unfamiliar enemy on an ancient battleground. With the help of a new ally (and her updated tech), Captain Cutter is determined to meet this fierce enemy head-on as he and his crew attempt to find a way home.
Headed by Atriox, the Banished are brutal warriors who seek to exploit the Ark for every resource they can get their hands on, and they will let no one stop them.
