What the developers have to say:

Why Early Access?

“Star Defender is a solo-developed experimental project built in Unreal Engine 5. Early Access allows players to support the game during its initial development phase and provide direct feedback on core mechanics, balance, and future features. This is not just early access — this is participation in the creative process.

Approximately how long will this game be in Early Access?

“We estimate that the game will remain in Early Access roughly until the end of 2026.”

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

“We plan to add expanded campaign options, new enemy types, bosses, and multiple endings. During Early Access, we will focus on refining core systems, including defense, combat, and progression.”

What is the current state of the Early Access version?

“The game features core mechanics including tower defense gameplay, planetary construction, a modular ship upgrade system, technology research, and the combat system. All systems are in an early but playable state and subject to ongoing refinement.”

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

“We plan to gradually raise the price as we ship new content and features”

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

“We plan to involve the community through regular feedback collection, polls on future features and balance adjustments, and open discussions via forums. Players will be able to influence the development and suggest improvements.
