The monsters must band together to keep the fearsome heroes away from their home. It's not like we're evil. We don't have any real plans for world domination or megalomaniacal schemes. Some of us just want a place to relax. Okay, maybe we have one or two teenagers locked in the dungeon to teach them a lesson about trespassing.

But then... suddenly we're on the guild's bulletin board, and every so-called hero can just barge into our home and loot our treasures?! I say - not on my watch!

Heroes Must Stay Out! is an asymmetrical, cooperative dungeon defense and deck-building game for 1-4 different monster clans. Improve your tactic decks to summon monsters, open portals, forge powerful weapons, explore spells, and tame pets so you can finally wipe out those pesky heroes!

Battle through various scenarios and make it clear to the heroes once and for all that this is your home! On your turn, you draw 5 cards and play them as cleverly as possible. Your hand cards allow you to move, activate game pieces, perform actions with game pieces, attack heroes, and move units. After each player, cards are drawn from the hero deck and executed.

Your goal as a team in each scenario is to survive the 3 levels of threat posed by the invading heroes by protecting the treasures in each room. If the main treasure is stolen, the game ends and you lose, but if you manage to protect the treasures long enough, you all win.
