BioEden Guides

BioEden looks simple for about twenty minutes. Then you place a second dome, discover that your solar network cannot carry it, notice your pollution has doubled, and realise the tutorial taught you the buttons rather than the game. These guides cover the parts BioEden does not explain.

Start here

• Beginner guideThe first-hour build order, and six mistakes that cost new Keepers hours.
• Second domeThe prerequisite chain for unlocking and paying for dome number two.
• Power & waterCable and pipe range, why buildings show as disconnected, and how to lay a grid you will not have to redo.
• Pollution & ImpactActive Regulations, Crisis Alerts, and how to bring a 95% region back down.

The four systems that decide whether your planet succeeds

1. The economy is a salvage economy

BioEden does not give you a mine and a production chain in the usual sense. It gives you a ruined planet covered in debris, and almost everything you build early is paid for by recycling that debris. Because the recycle button refunds materials, the correct instinct in BioEden is the opposite of most builders: place things speculatively, see the effect, tear them down. There is no punishment for it.

2. Power and water are two separate networks

Solar generates electricity; water distributors move water. They use different connectors and they fail differently. A building can be fully powered and still non-functional because no pipe reaches it, and the UI does not always make the distinction obvious. This is the single most common source of "my building is not working" confusion in BioEden.

3. Pollution is regional, Impact is global

The globe widget in the HUD shows the pollution level of the region you are currently looking at — official screenshots show values from 8.1% in a healthy Jungle to 95% in a Purple Crystal Prairie. Impact Level is a separate, planet-wide number. Regional pollution affects the animals in that region. Impact Level is what triggers the Collective's Active Regulations and, past a threshold, a Crisis Alert with Charles telling you plainly that you are doing more harm than good.

4. Research is per-biome

Research in BioEden is organised as a Biome Knowledge Tree, and it levels per biome rather than globally. One official Collective Request asks the player to "raise Knowledge of Prairie to Level 6 in the Biome Knowledge Tree", which tells you two useful things: knowledge levels go at least to 6, and they are tracked separately per biome. If you intend to specialise in one biome, your research spending should follow.

A note on difficulty

BioEden is genuinely relaxing and genuinely forgiving, and if you want to build pretty domes and never look at a number, you can. But the systems underneath reward planning, and the mid-game does have failure pressure — just expressed as regulation and restriction rather than as a loss screen. Players who came in expecting zero friction and hit an Active Regulation for the first time are often surprised. That is not the game breaking; that is the game's one real difficulty curve. The pollution and Impact Level guide covers how it escalates and how to reverse it.
