About the game
What you do in a play session
If you dig the scientific and challenging vibe of the BIOS series but found Megafauna a bit too... grand, then Mesofauna might be your new favorite! Think of it as a more accessible and focused version of the experience, where you'll dive into the evolution of smaller, but no less important, creatures on a constantly changing planet. This game keeps the essence of ecosystem simulation and evolution but with a leaner ruleset and fewer elements to manage. The goal is to attract a wider audience without losing the depth that fans of the series expect.
The modular board ensures that each game is a new adventure, with different configurations for you to explore. You'll use the open drafting mechanic to grab the best cards and actions, all while competing for area control and trying to adapt your species to drastically changing climate and environmental conditions. It's an evolutionary race where only the most adaptable survive and thrive. Player interaction is tense, as one player's decisions affect everyone's ecosystem.
Bios: Mesofauna is a game that rewards strategic planning and the ability to adapt to the twists of fate (and the climate!). If you enjoy games with strong themes, clever mechanics, and a challenge that keeps you thinking for hours, this is a sure bet. It's a great entry point to the BIOS series or a fantastic addition for existing fans.
