By the end of the beta, it'd be funny if everything ended up being "more in line with Warhawk". Would be nice. Warhawk plus BnB done properly with premade bases is all I wanted.
Yer pressing triangle will bring up the menu of RTS options. Each building costs a different amount of rift but it will tell you if you can 'afford' it when you select it. Bases start with a pre-built bunker, hawk platform and buggy platform - use your rift wisely as maximum for team is 32 builds at any given time
