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?

“NERMIUS is a two guy developed project built with a clear vision but room to grow. Early Access allows real players to shape the balance, pacing, and content before the full release. Your runs, your feedback, and your deaths matter.”

Approximately how long will this game be in Early Access?

“Approximately one year. This estimate may shift depending on the scope of updates and community feedback, but the goal is a full release within that window.”

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

“The Early Access version contains the core survival loop with one fully playable planet, multiple shells, and progression systems. For the full release, we plan to add several additional planets with unique enemies and bosses, a story mode that expands the Saturn Acme Corp narrative, and standalone minigames set within the same universe. The full version is intended to be a significantly larger and more complete experience.”

What is the current state of the Early Access version?

“The current build includes two planets, shells, wave-based survival, bosses, and meta-progression. Core gameplay is complete and stable. More playable shells are planned before the Early Access release.”

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

“The price will increase slightly when the game leaves Early Access. We want to reward players who support the game early with a lower price during development.”

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

“We plan to actively read and respond to community feedback through Steam Discussions and reviews. Player input will directly influence balance decisions, new content priorities, and quality-of-life improvements. Regular update posts will keep the community informed on what changed and why.”
