How about a world...Thats desert, and has two Bases...With...Vehicles..Like..Tanks..and...uh...M achine gun totting Vehicles..AND AND...a hand held Machine gun that deploys when activated, and acts like a turret..and a Engineer that can repair buildings. =p
Lets see what buildings I have in mind first for buildings, although:
Power Plant - Supplies Power...If destroyed...Well..Lights are out inside the buildings.
Barracks - A barracks..Somewhere to hang out while waiting for the enemy?
Repair Pad - Place for Vehicles to Repair.
Construction Yard - Repairs structures slowly.
Vehicle Pool - Can you guess? Vehicle Storage! =p
Like the idea? =p
Imagine seeing a Tank battle in the middle of the Desert. =p
