NOTE. Because Project Wunderwaffe: Prologue is not the full game, you cannot save. Project Wunderwaffe: Prologue is only available in survival mode and has one difficulty level: hard. It is possible to explore Tier I
in its entirety.
Tiers II and III, three difficulty levels (easy, medium, and hard), and all game content, along with the ability to save, are only available in the full version
of Project Wunderwaffe.
