While it takes ground troops to hold any position, it’s the land, air, and space vehicles that captures everyone’s imagination. Accelerate your Albedo campaign with larger battles on the scale of platoons, squadrons, or wings. Field vehicles featured in Steve Gallacci’s comic, or design your own! Structural Integrity increases the stakes of your game from small tactical battles to all-out interplanetary war.
