What is IDUN Prologue - Frontline Survival?

This free, single-player prologue combines top-down real-time strategy with arena-based defense. In procedurally generated arenas, you deploy units, use destructible terrain, and pursue different mission objectives. It samples a larger game with a limited selection of turrets, tools, and heroes.

For you if...

+you enjoy balancing resource gathering with frontline defense
+you like building different strategies around random upgrade choices

Not for you if...

−you prefer slow planning without real-time combat pressure
−you want a full-length campaign rather than a limited preview
