Iron Sky Invasion creates a trashy, funny atmosphere, like the film does. However, it has a simple and slow gameplay with really boring missions. Maybe there are some few Iron Sky fans, who like the game, but if you like complex, tactical space battles, Iron Sky Invasion is not the right game for you.

Iron Sky: Invasion is a space simulation game with cool and fun gameplay, strongly affected by a lack of technical deficiencies and a very repetitive game structure.

Iron Sky: Invasion isn't a bad game. There is a chance, that some fans of space flights and fights will enjoy it. But you need to remember, that it's a simple game that looks more like a complex indie game and if not for the movie tie-in, no one would have heard about it. The politics plays no part in the gameplay, the fights are slow and have a bad difficulty balance. A good idea is not enough to make an interesting game.

Mediocre adaptation of a mediocre movie gives you exactly what you’d expect – stereotypical gameplay and zero fresh ideas. [Jan 2013]

Invasion shows how a fast, properly executed gameplay can be turned into a tedious monstrosity. [CD-Action 02/2013, p.68]

Iron Sky: Invasion takes off in an interesting fashion but soon reveals itself as a dull experience. Even fans of arcade shooters could find it too repetitive to play it until the very end.
