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?

“ I believe player feedback is crucial to shaping Space Mantlet into the best version it can be. As a solo developer, Early Access allows me to involve the community early in development — testing features, refining balance, and helping prioritize what’s fun and engaging. Space Mantlet is a unique RTS experience, and your input will directly influence its evolution toward full release.”

Approximately how long will this game be in Early Access?

“The game will stay in Early Access until it feels complete and polished, which I currently estimate at around 12 to 18 months. However, this may adjust based on feedback and scope changes.”

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

“ The full version of Space Mantlet is planned to include four additional playable factions, complete with their own units, vehicles, and mechs. I also aim to deliver 8–10 handcrafted campaign missions, enhanced audio design and voice acting, more skirmish maps, and a wider variety of terrain types to deepen strategic options and replayability.”

What is the current state of the Early Access version?

“ The current Early Access version of Space Mantlet includes one playable faction, four skirmish maps, and a basic tutorial to help players get started. Core mechanics like unit deployment, base setup, and point-to-point combat are functional, with more features planned throughout Early Access.”

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

“The price may increase as more content and features are added during development. I plan to start with a lower price during Early Access to encourage community feedback and support, and gradually adjust it toward full release to reflect the game's growth and value.”

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

“I plan to involve the community through regular updates, open communication, and feedback-driven development. Players will be able to share their thoughts on balance, features, and bugs through the Steam forums and official social channels. I’ll prioritize suggestions that align with the game’s vision and iterate based on what’s fun and meaningful for the community. As a solo developer, your feedback will directly shape how Space Mantlet evolves.”
