The preview reconfirmed the existence of two-player online cooperative play for Halo Wars' story-driven campaign mode, as initially revealed at the time of the title's original announcement. The game is also expected to support six players in multiplayer matchups over Xbox Live.
Also of note was the revelation of the title's resource system. Unlike other RTS games which might have you gathering wood, iron, or Vespene gas, Halo Wars only requires "supplies". The single resource system is meant to streamline action and keep things simple but stategic, allowing players to focus on battle over preparations.
"The economy is simple but meaningful," Ensemble designer Dav Pottinger told GamePro. "All the big strategy decisions remain, but the game style is more adrenaline-filled."
Halo Wars is expected to drop later this year.
so no special build.. no timing required. Just one resource sounds lame.
world in conflict and C&C series was built on this, and surely you can't argue they werent fun?
