Contours: the strait's elevation, from the game's own map data

01

Fly low. Stay hidden.

Terrain masking is how attack helicopters survive: keep a hill between you and the radar, pop up, fire, and drop back down. Terrain Mask is built around it, on maps made from the real ground.

  • Real ground to hide behind

    Eight theatres built from real elevation, sea-floor and land-cover data, with OpenStreetMap roads, ports and towns where they really are. The terrain is your cover: drop below the ridge line and the radar loses you.

  • A war on its own clock

    Every theatre has a dynamic war: brigades, ferries, air strikes and supply, fought hour by hour on the real map. Every six hours of war time you pick sorties against what has been seen, and what you destroy is gone from the war.

  • Three cockpits, modelled

    The RAH-66 Comanche stealth scout, a heavy attack helicopter with a gunner and a naval attack helicopter with a copilot. Each has its own cockpit: head-up display, three multifunction screens and lamps that dim at night.

  • Stick, throttle, collective, pedals

    Fly with keyboard and mouse, an Xbox controller, or a flight stick, HOTAS, collective lever and rudder pedals, up to four devices at once, read directly. Rebind every control and tune every axis.

  • Co-op for two

    Host a mission or a war sortie and fly it with a friend through Steam: one briefing, two aircraft, a shared debrief.

  • Weather and night

    Golden hour, dusk, and nights with moon phases and lit towns. Rain squalls, thunderstorms with lightning, and dust-storm fronts you can see coming. Night-vision goggles and a thermal sight are part of the cockpit.

03

Eight theatres

Each map is a real stretch of coast, strait or frontier at full scale, with its own campaign, its own war, Instant Action and Free Flight. The contour tile on each card is drawn from that map's elevation data; the grid label is its centre.
