About the Game

Manipulate a swarm of insect minions in fast-paced, team-based battles. Coordinate with fellow fungi to outwit opponents and fight for a taste of victory! Inspired by arcade hits like Killer Queen, Shroom Siege offers  easy-to-learn gameplay mechanics and Japanese-inspired ink-wash designs, providing depth and complexity for seasoned shrooms.

Join the fight from wherever you are! Whether you’re sharing a couch with future rivals or hopping into a match from across the world, Shroom Siege remains dynamic and tailored to each unique gaming setup.

Bring the entire community together with cross-play across Steam and Nintendo Switch platforms. It’s always a good time for a siege, regardless of location, platform, or setup!

Taking cues from the arcade hit, Killer Queen, Shroom Siege introduces its unique gameplay mechanics. It's a game that's easy to pick up, yet offers depth and complexity for those who crave a strategic challenge.

Claim victory in one of three ways:

  • Shrine Victory: Deliver spores to all shrines across the map and maintain control of every shrine to succeed!

  • Shogun Victory: Possess a Shogun warrior and defeat the opponent’s Shogun thrice!

  • Poop…Victory?: Push a giant dung ball from one side of the map to the other to claim this satisfying victory!

An insect minion must be possessed and controlled by a shroom at all times, adding an additional layer of complexity to each battle.

Dive into fair and engaging battles with Shroom Siege’s balanced matchmaking system, which pairs teams of similar skill levels. Both fresh and seasoned aspiring fungi can find matches challenging and fun for both parties.

Designed with controllers in mind, Shroom Siege is playable via keyboard and mouse, as well as controllers of all types. Find the winning playstyle with a simple control scheme accessible for all players!

Shroom Siege offers a balanced blend of strategy, action, and fun. So, gather your friends or join the online community, and let's start the siege!
