How to read version numbers
- Launch Monster Lab Simulator.
- Check Settings or the main menu for a version string (e.g.
v0.2.3.3or a Steam build id). - Record the full string with any recipe, economy, or achievement test you log.
- Prefer Steam news + in-client version over third-party “update” videos that mix older footage.
Why version tracking matters
Early Access can change:
- Economy values (sell prices, essence costs, order rewards)
- Breeding / hatch mission conditions
- Merge Machine and Extraction behavior
- Achievement conditions
- Habitat and Battle Room flow
Data without a version number is hard for other players to trust.

How to submit patch data
If you have a newer Steam news entry or an in-game version string we missed:
- Note date, exact version, and what changed for players (not marketing fluff).
- Prefer a Steam news URL or a short clip + version screenshot.
- Do not invent patch numbers or copy lists from unrelated “monster lab” games.
