About this board game
Mutagen is a customisable worker-placement game for 1–4 players, with games lasting around 90 minutes. Set in a 1920s biopunk universe, it challenges players to become the next Keeper of the Great Shard.
The Great Shard is a powerful element discovered during the final years of the industrial revolution. Its energy transformed the world, accelerated industry, and created creatures and phenomena beyond the laws of nature. Now, the Keeper’s unnaturally extended life is nearing its end, and four Mutagen are competing to inherit their position of power.
Each player controls four workers, and every worker reacts differently to the location where it is placed. Whenever you deploy one, you activate the location’s main action as well as an additional action determined by that worker’s colour. Biological upgrades can further enhance your workers, unlocking their full potential and giving you new ways to outmanoeuvre your opponents.
- Place workers to activate locations and colour-based abilities.
- Infuse workers with biological upgrades.
- Collect elements from floating cities.
- Trade elements for objective cards or invest in dominance over particular elements.
- Harness elemental energy to upgrade your airship.
Every location has been transformed by vast bio-enhanced changes, creating a world where each decision can contribute to your growing score. As the four years, or rounds, pass, build influence and accumulate points while demonstrating your command of the Great Shard’s power.
At the end of the game, the player with the most points wins and earns the right to succeed the Keeper. With its reactive workers, biological customisation, elemental resources, and richly altered setting, Mutagen puts the future of a remarkable biopunk world in your hands.
