Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“IONHAVEN: Battery Heist already has a playable core built around stealth, energy management, territorial expansion, and persistent progression. Early Access gives us the opportunity to refine these interconnected systems with player feedback.
We are especially interested in feedback on AMP balance, raid pacing, procedural layouts, district identity, faction events, difficulty, and long-term progression. Our goal is to expand the game while preserving the tension of every movement consuming the same energy that keeps the player alive.”

Approximately how long will this game be in Early Access?

“We currently expect IONHAVEN: Battery Heist to remain in Early Access for approximately 12 months. This estimate may change depending on player feedback, balancing needs, technical improvements, and the scope of the systems developed during Early Access.”

How is the full version planned to differ from the Early Access version?

“We plan to expand the variety and strategic depth of the game throughout Early Access.
Our current priorities include making each district affect gameplay more meaningfully through unique hazards, enemy compositions, objectives, resources, extraction conditions, and persistent sector consequences. We also plan to deepen faction and territorial systems, add more raid objectives, enemies, tools, upgrades, events, and progression options.
Other planned areas include Steam achievements, improved AI coordination, additional accessibility and quality-of-life options, expanded narrative content, balance and performance improvements, and further localization polish.
These plans may evolve in response to community feedback and development testing.”

What is the current state of the Early Access version?

“The current version provides a complete playable progression loop. Players can infiltrate procedurally assembled locations, manage AMP as both life support and an action resource, avoid or disable security forces, complete objectives, collect loot, and reach extraction.
Between raids, players can select sectors on a persistent 78-sector city map, capture territory, encounter faction conflicts and daily modifiers, purchase equipment from the market, manage inventory, and invest in permanent workshop upgrades.
The current build includes four district themes, multiple enemy and security types, different raid objectives, tools and consumables, difficulty settings, save slots, and interface localization in English, Ukrainian, Italian, Japanese, and Simplified Chinese.
As an Early Access release, the game is playable but still undergoing balancing, interface improvements, content expansion, and technical polish.”

Will the game be priced differently during and after Early Access?

“We plan to offer the Early Access version at a lower price than the full release. The price may increase as substantial new content and features are added, and we will communicate any planned changes in advance.”

How are you planning on involving the Community in your development process?

“We plan to collect feedback through the Steam Community Hub, player reviews, bug reports, and our development channels.
Player feedback will help us evaluate AMP economy and difficulty, stealth readability, procedural generation, district variety, faction consequences, progression pacing, and the usefulness of tools and upgrades.
We will share development updates and changelogs, highlight systems currently being tested, and use recurring player feedback to help prioritize balancing, quality-of-life improvements, and future content.”
