IDUN or IDUN - Frontline Survival is a real-time strategy and tower defense game developed by IDUN Interactive. In this singleplayer game you can extract resources, upgrade technologies, control your heroes on the battlefield and defend your planet against enemy swarms, while you can move the turrets at your own will.
As a game that combines RTS and tower defense mechanics, "IDUN" features overwhelming enemy swarms that fill the screen. Players often face vast hordes of enemies in a battle for survival. With fully destructible terrain and smooth AI pathfinding, the swarms can attack from multiple directions, making the battlefield dynamic and unpredictable.
Players must balance the micro-management demands of RTS gameplay, coordinating diverse combat units to maintain a solid frontline. At the same time, they must strategically plan defenses like in a tower defense game, adjusting to complex and multi-layered maps.
Beyond the battlefield, players will use the resources gathered from combat to plan out technology upgrades, ensuring they have the necessary tools to face the growing threats.
The game released on 20 January 2025 for PC (Windows, macOS, Linux).
KEY FEATURES:
- Fully Simulated Battlefield: The battlefield changes over the course of the battle. Craters are formed from explosions. Soon after the simulated smoke settles that very crater can be filled with blood from the enemies, changing the outcome of the battle.
- Blue-Collar Story Campaign: Embark on an adventure with the eclectic crew stationed on this outer rim drilling station, where a captivating tale of love, deception, and death awaits. 7 to 135+ hours of fun!
- Power at you fingertips: You'll have access to a vast explosive arsenal of turrets, tools, and heroes. All of which can be upgraded to increase the odds in your favor. Just point where you want the destruction to happen.
- Overwhelming swarms of enemies filling the screen
- A blend of RTS and tower defense mechanics with real-time troop management
- Fully destructible terrain and smooth pathfinding AI for more complex and varied enemy attack patterns

IDUN Interactive was founded in 2022 by Gustav Hagerling. He is a veteran in the game industry who has worked on several AAA titles from Battlefield to Crysis as a Lead VFX. But his endless passion for game development drove him to start his own studio. The first game, called IDUN, started development as a single developer before the studio was organised into a small team. The smaller team reflects the greater flexibility, attention and individuality needed to achieve their goals: shorter development cycles, community-based open development, a focus on fast-paced gameplay and customisability. 1
The game is primarily being developed for PC (Windows, macOS, Linux), with iOS and Android also planned for release, and potentially coming to PlayStation, Switch and Xbox. 2
IDUN, named after the Norse goddess of youth, begins as humanity lands on a planet bearing her name. This unique game blends real-time strategy (RTS) and tower defense mechanics, allowing players to move turrets freely. The primary goal is to extract sufficient resources from the planet before being overrun by waves of enemy forces.
The game includes a traditional story-driven campaign, alongside various challenging modes. In the campaign, players follow the protagonist as they embark on a journey across the IDUN planet, where a gripping tale of love, deception, and death unfolds.
The challenge modes include different gameplay scenarios such as defending collection points, escorting nuclear vehicles, surviving as a group of survivors, and protecting mining carts. Players will face off against swarms of enemies with varying difficulty levels, earning resources to advance their technology and strengthen their forces.
