About IDUN

Welcome to IDUN, a new breed of defense RTS where explosive single-player action meets a gripping story campaign.

Engage in a compellingly chaotic combination of RTS action and tactical tower defense to wipe out relentless alien swarms overwhelming the screen. Command a varied arsenal of combat tools in real-time, from repositionable drag-and-drop turrets to point-and-shoot orbital cannons, leveraging their strengths to overcome challenging scenarios.

Explore several diverse modes and complete fist-pumping missions, including defending the collection base, escorting nuclear vehicles, and protecting mining carts. Execute a strategic plan of defense by deploying destructive tanks, blade-spinning fans, flesh-melting turrets, and sturdy barriers to block vicious waves of extraterrestrial vermin.

Real-time Tactical Flexibility

Break free from traditional tower defense gameplay—deploy and reposition your units freely, taking full command of the battlefield.

Dynamic Battlefield

Experience ever-changing missions as the battle against relentless enemy swarms reshapes the terrain. Destruction and enemy remains create new challenges and opportunities, demanding constant tactical adaptation.

Persistent Tech Progression

Advance through a robust tech tree, upgrading your space station and unlocking devastating turrets, elite troops, and tactical tools to outlast the endless onslaught.

High Replayability

Rogue-lite elements ensure every run is unique, filled with fresh challenges, unpredictable encounters, and new ways to master survival.

The Outer Rim

Dive into a fully voiced story where the relentless attacks are just the beginning. Join the crew as the story unfolds in unexpected and game-changing directions.

Play Your Way: Full Control Anywhere

Enjoy the freedom to play IDUN however you like! The game offers seamless support for Mouse & Keyboard, Gamepad, Touch, and is now fully optimized for Steam Deck.

Take advantage of extensive customization options for both visuals and controls, ensuring the perfect gameplay experience tailored to your preferences.

IDUN for PC starts at €7.72 (€8.01 with fees) at G2A, a Steam key, which is 25% under the €10.75 (no fees) it costs on the official store.

That €7.72 (€8.01 with fees) already includes the GCKG2AC9Q3M coupon, so apply it at checkout or the store will show you a higher price.

Worked out from 564 daily records of the Steam Key for IDUN across 5 stores. See the full price history.

The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.

Can you activate IDUN in US?

All 3 offers are Global, so the code redeems on any account no matter where it was created.

Information about IDUN for PC


IDUN, inspired by the Norse goddess of youth, takes us to a world where humanity explores a hostile planet that bears her name. This game combines real-time strategy with intense defense mechanics, while a captivating narrative unfolds in the background. Your main mission is to extract the necessary resources from this unforgiving environment before being overwhelmed by massive waves of enemies.

The game introduces a novel dynamic that allows you to move turrets in real time, which adds a unique strategic level. In addition to defending your position, you will be part of a story rich in twists and turns involving love, betrayals and sacrifices. Some members of your team can even become playable heroes on the battlefield, bringing unique abilities to change the course of engagements.

You will face hordes of enemies that fill the screen, with an advanced AI system that allows for complex and varied attack patterns. The fully destructible terrain adds an extra layer of strategy as you must adapt your tactics as you research and upgrade your arsenal to meet increasingly tougher challenges, including specialized enemies, harsh environmental conditions, and gameplay-altering modifiers.

The game offers a unique blend of tower defense, troop management, and combat in both ground and air operations. Each mission is designed to offer fresh challenges, forcing you to think strategically and specialize in your approach. As you progress, you'll have the ability to customize your weapons and units, optimizing your playstyle to overcome obstacles.

Most common FAQs when buying IDUN for PC in digital format:

It is a key that will allow you to download the game IDUN on your PC from official download platforms.
As of 20/10/2026, in United States, the best price we have found in our selection of online stores that include the key for IDUN on PC is €7.72 (€8.01 with fees).
The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format. You just need to redeem the key in your account to download IDUN to your game library. The account format requires more complicated steps and is more prone to errors during activation.
The only issue we’ve encountered in 13 years is receiving a duplicate key that doesn’t work. In that case, simply contact the store where you bought IDUN, and they will provide a new key. You can also contact us, and we’ll help you out.
Delivery times vary by store. For example, in the case of Instatgaming, Eneba, G2a, or Kinguin, delivery is usually instant or takes just a few minutes. These stores rarely delay game deliveries.

Other stores may take 30–40 minutes depending on game availability. On release days, delivery times may be slightly longer.

If you notice an unusually long delay, contact the store or us, and we’ll resolve it as quickly as possible.
At Gocdkeys, we only list the most well-known stores that have passed our quality checks. One of the most important factors is good customer support, and all listed stores offer it.
