The Moon Nazis are sending reinforcements — apparently, megalomania scales just fine in the Moon Reich.
The Second Fleet adds a new scenario to Iron Sky: Invasion, blending space combat, real-time strategy, and tower-defense in Earth’s orbit. The pilot becomes a space admiral, the familiar real-time map becomes a command center — and “I hope somebody has a plan” turns very quickly into “Unfortunately, I’m the plan now.” Whether you take the fight deep into enemy lines or coordinate Earth’s fleet from the rear is up to you.
As an endless stream of Moon Reich ships closes in, Earth’s fleet rallies for defense. While the battle rages, you stay active in the fight, position the remaining defenders, call in support, and hope this ragtag pile of orbital stopgaps holds together long enough to shoot the Moon Nazis back to the Moon.
Stop the Fourth Reich’s renewed invasion before the next orbital round reaches Earth. And show the Moon Nazis that improvised defense can hit back surprisingly hard.
