About the game
Biotope sets out to be one of the most thorough and true-to-life fish tank simulators available. It gives players the tools to design intricate aquatic ecosystems and mirror how a tank's plants and its fish actually grow and behave over time. The title is in early access and was both developed and published by MBL Development in 2019.

Are keys from these stores legal?
Buying is legal — keys come from the grey market, so a small deactivation risk exists. So before paying, check the seller's buyer protection.
Which key region should I pick?
Global activates everywhere. Regional keys (Europe, North America, RU-CIS) only work on accounts from that region — use the Region filter to match your account.
What is an activation platform?
The service where the key activates — Steam, GOG, Epic or the publisher's platform. A key for one platform won't work on another, hence the separate filter.
What's the difference between editions?
Standard is the base game; Deluxe usually adds an expansion or bonus content. The edition filter shows exactly that variant, with no mixed prices.
