An official sci-fi space combat simulator based on the cult film "Iron Sky", developed by Reality Pump Studios and published by Topware Interactive. Set in a near-future universe, the game puts players in the cockpit of advanced starfighters to defend Earth from the invading Fourth Reich—Nazis who secretly built an armada on the moon and launched a brutal space blitzkrieg against humanity.

Experience genre-blending gameplay that fuses space dogfighting simulation with real-time strategy elements. Master innovative energy management by redistributing power between engines, shields, and weapons to adapt to battles. Explore a vast open-world space battlefield (no segmented missions) to protect Earth’s satellites and bases, assault giant Nazi space zeppelins, and scavenge resources from destroyed enemy ships for upgrades.

This global Steam key redeems worldwide via the Steam client, unlocking the full single-player experience. Optimized for diverse PC configurations, it requires a minimum of 2GB RAM, 1.5GB storage, and DirectX 9.0c (recommends DirectX 11 for enhanced visuals). Supports 7 languages (English, German, French, Italian, Spanish, Czech, Polish) with varying interface and audio support, plus partial controller compatibility.

Leverage a real-time space map to track Nazi forces and ongoing battles, with the ultimate goal of destroying their hidden moon base. Enjoy high replayability through side missions and a challenging scoring system, paired with spectacular ship-to-ship combat powered by the GRACE2 engine. A must-have for fans of sci-fi action and cult film adaptations, blending over-the-top humor with tactical depth.
