Any of the Vehicles that have NEVER been used in a Halo FPS before.
Halo Wars has an awesome Catalog. the Rhino, the Covenant Vampire, and the Wolverine would be some pretty nice additions.
I’m still holding out for at least 1 more team based vehicle.
What if there were player controlled Mammoths and Scarabs, and that part of a Warzone gametype was to determine which team could destroy the other’s super vehicle?
that’d be dope.
