How to Read Version Numbers
Monster Lab Simulator uses a version string visible in-game (exact location: check Settings or the main menu title screen). The format may follow Steam build numbers or an internal versioning scheme.
Finding Your Version
- Launch Monster Lab Simulator.
- Open the Settings menu or check the main menu for a version string (e.g., "v0.X.X" or a Steam build number).
- Note the full string exactly as shown — do not abbreviate.
- Record this alongside any data you collect (recipes, economy values, achievement conditions).
Why Version Tracking Matters
Early Access games can change:
- Economy values (sell prices, essence costs, order rewards)
- Breeding output pools
- Evolution Machine behavior
- Achievement conditions
- Habitat recovery rates
Data recorded without a version number may be misleading or harmful to other players.
Tip: Every guide on this wiki includes a "Version Notes" section. Always cross-reference the version when using community data.
