Why Early Access?

“Metabolis is a "material flow" simulation where water, power, sewage and traffic all live on one connected set of physics. In a game like this, the fun is decided by how thousands of different player-built cities stress the systems — far more variety than we can generate on our own. We chose Early Access so we can tune balance and deepen the simulation together with the community from an early stage. The core mechanisms — pollution cause-and-effect, infrastructure-gated growth — are already working; the stage we want to go through with players is turning that core into long-term depth.”

Approximately how long will this game be in Early Access?

“We currently expect roughly 1 to 1.5 years, with quality as the priority. The actual length may shift depending on community feedback and on how the additional systems described below progress.”

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

“For the full version, we are planning (subject to change as development progresses):

A full waste chain (collection → landfill / incineration / recycling)
Nuclear power and its fuel cycle, from spent-fuel storage to disposal
Public transit (bus, rail) affecting traffic volume and demand
Expanded effects of parks and landmarks on satisfaction and land value
More building variety, plus ongoing economy and growth balancing

The core of the game — hydrodynamics, power, water/sewage, traffic, staged growth — is already playable at the start of Early Access. We see the full version as adding systems on top of that foundation.”

What is the current state of the Early Access version?

“The core loop is playable from start to finish:

A genuinely simulated hydrology (rivers that swell, dry up and flood) with full water infrastructure: intake → purification → supply, and sewage → treatment → outflow. Untreated discharge fouls the river, and polluted intakes come back to your city as disease
A power grid (thermal / wind, power lines and substations, brownouts on shortage)
Residential / commercial / industrial zoning with eight growth stages from hamlet to metropolis
Per-vehicle traffic (signals, intersections, pedestrians, emergency responders) and external connections
Terraforming, weather, a day/night cycle, save/load, and a photo mode

We are currently focused on balancing and polish; some rough edges remain (UI refinement, and some facility effects not yet implemented).”

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

“During Early Access the game will be priced to match its current scope. We plan to gradually raise the price at full release to reflect the content and features added along the way.”

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

“The Steam Community Hub and discussion boards will be our main channels for feedback, bug reports and balance suggestions. Patch notes for each update will explain not just what changed but why, and we will regularly share development notes on what we are fixing now and trying next. Because Metabolis is balanced against real player-built cities more than anything else, the saves and screenshots you share will feed directly into how we tune the simulation.”
