BioEden Beginner Guide

The BioEden tutorial teaches you which buttons exist. It does not teach you the order to press them in, and the gap between those two things is where most new Keepers lose two or three hours. This guide is the opening you should actually play.

Before you build anything: survey

The single most valuable action in early BioEden is walking your Keeper across the hex tiles around the landing zone and looking at what is there. Debris sites are the foundation of the entire early economy — they are what you recycle into the materials that pay for your first solar pylon, your first water distributor and your first dome. They are also finite and fixed in place.

Players who build first and survey second routinely place a structure on top of a tile they will later wish was free, or run a cable in a direction that turns out to have nothing worth reaching. Spend the first few minutes walking. Nothing is chasing you.

The opening build order

1. Salvage every debris site you can reach. This is your entire starting budget. Do it before you spend anything.
2. One solar pylon. One. New players frequently build a second because the camera made them think the first did not place, then wonder where their materials went.
3. One water distributor. Power and water are separate networks in BioEden and you need both before anything meaningful works.
4. Shortest possible cable and pipe runs. Range is limited. A tidy short grid now saves a rebuild later.
5. Your first dome, then an Incubator inside it. The Incubator is what converts banked DNA into a living animal.
6. Open the Bestiary and look before you spend. Landowl and Ributs are already unlocked in the Jungle tab. You do not need to spend DNA to get started at all.
7. Hatch Landowl first. It wants 20–45°, 55–90% humidity and two Ferns — the widest, most forgiving band in the documented roster.
8. Only then start unlocking. Fimble at 3 DNA and Slink at 5 are the cheap next steps.

Six mistakes that cost new Keepers the most time

1. Building before surveying

Covered above, and it is the big one. Everything downstream of a bad opening layout is more expensive.

2. Building a second solar pylon by accident

This happens constantly. The camera in BioEden takes some getting used to, and a placement that looks like it did not register often did. Check your power total before you place a duplicate.

3. Starting with industry instead of infrastructure

An Orb Factory is exciting. It also costs 1500 + 1000 materials, draws 50 power and carries a +35 pollution effect. Building one before you have a stable power network and a functioning dome is how a new save ends up with high pollution and nothing to show for it.

4. Cloning your first dome

Once you get one Jungle dome working, the temptation is to build the same dome again. Resist it slightly. A second dome in a *different* biome unlocks a different Bestiary tab and different research, and the game's progression assumes breadth eventually. Cloning is not wrong — it is just the cheapest possible option, and cheap options compound into a slow campaign.

5. Housing predators with prey

Diet is a requirement the Bestiary does not put a number on. Put a carnivore in with your herbivores and it will eat them, no matter how perfect the climate is. See carnivores vs herbivores.

6. Ignoring the pollution number on the globe

The globe widget in the HUD shows the pollution percentage of the region you are looking at. It is easy to never look at it for the first hour. Official screenshots show a healthy Jungle at 8.1% and damaged regions at 75% (Burnt Tundra) and 95% (Purple Crystal Prairie), and the difference matters both for your animals and for your Impact Level.

What "no fail state" actually means

BioEden has no game over screen and every building refunds materials when recycled, so you cannot permanently ruin a save through bad building decisions. That is genuinely true and it is the reason the game feels relaxing.

What it does not mean is that your choices do not matter. Let Impact Level climb far enough and the Collective imposes Active Regulations — restrictions on what you are allowed to do — and raises a Crisis Alert, with Charles telling you outright that you are doing more harm than good. You will not lose the save, but you will spend a long time digging out. Treat pollution as the one number worth watching from hour one.

Understanding the three animal stages early

The most common mid-tutorial confusion in BioEden is thinking an animal is "done" once it is out of the Incubator. It is not. Every species moves through Biome (it can survive here), then Residency (it chooses to stay), then Mating (it reproduces). Those are three separate tabs in the Bestiary with three separate requirement lists. Climate satisfies Biome. Residency wants decoration, water access and space on top. Mating wants a partner and no active stressors on top of that.

Knowing this early saves you from the classic loop of re-checking the thermostat over and over while the actual missing requirement is a watering hole.

A sensible first-session goal

Do not try to do everything. A good first session in BioEden ends with:

• Every reachable debris site salvaged
• One power network and one water network, both tidy
• One Jungle dome with Landowl at Residency, not just Biome
• Regional pollution still under 20%
• 8 or more DNA fragments banked toward Fimble and Slink

That is a modest list and it puts you in a genuinely strong position. From there, read how to build a second dome and power and water, which are the two walls most players hit next.
