About Myriad Mayhem
Myriad Mayhem is a hero-siege game with ability-driven combat and roguelite runs. You defend your territory from relentless enemy attacks, grow stronger, then push back and drive the enemy off the map before they overwhelm you.
Conquer and expand
Claim new lands to grow your kingdom. You can fortify the frontier with towers and barracks, or develop a well-protected region into a settlement that supports your campaign.
Abilities and gear
Conquests may reward you with gear, expanding your arsenal and giving you ways to specialize your playstyle between runs. Each ability has its own talent tree that can change how it works. For example, you can shape Firebolt to explode on impact, apply a scalding burn or embed a volatile core that detonates on death. Choose your gear and abilities, then develop them to suit your approach.
Permanent upgrades
As you rank up, you earn progression points to spend on permanent upgrades that increase your strength and improve your odds in later runs.
