The player has at their disposal a variety of experimental, secretly manufactured space fighters, and are tasked with keeping these Moon Nazis off our beloved Planet Earth. "Iron Sky: Invasion" will bear the major underlying theme of politics: everything, even defending your planet from "luna-r-tic" villains, requires skillful political maneuvers. You will need to know who you are fighting for, whose boots you are stepping on, and choose your friends, or more importantly, enemies carefully.

Iron Sky: Invasion has been developed in close connection with the filmmakers, who have been helping tie both the visuals and storyline tightly into the Iron Sky universe. Jussi Lehtiniemi from Troll VFX, CG-company responsible for all the visual effects of Iron Sky, has captured space ship models directly from the film – the space Zeppelins, the Nazi invasion fleet, and the Earth fleet – as well as creating additional ship designs well suited to the Iron Sky universe.

Originally scheduled for Nov. 9, 2012, Topware has decided to delayed the game to give the developers some extra polishing time.

Alexandra Constandache, CEO of TopWare Interactive: "After thoroughly testing the game within the community, we’ve listened to the feedback and have decided to implement some positive changes that will allow us to retain our high quality standards. We all here at TopWare Interactive and Reality Pump are huge fans of space combat simulations and want to combine the humor and bizarre world from the movie "Iron Sky" with great game features.”
