Dungeon defense board game adaptation Keep the Heroes Out coming to Nintendo Switch

Today, board game creator Brueh Games and video game developer YarnCat Games announced Keep the Heroes Out, their video game adaptation of Luís Brueh’s acclaimed strategy board game. Look for it on December 9, 2025.

Keep the Heroes Out – which was funded on Kickstarter – is an asymmetric, cooperative dungeon defense game that supports up to four players. In the game, you’ll play as the monsters protecting their hard-earned treasures against invading hordes of “heroes” trying to steal it.

Here’s a bunch of additional information:

Monsters may die, which is tragic, but you can always bring them back to the dungeon! So you are never eliminated from the game, however, treasure gone, is gone forever.

Each player chooses one of the monsters to play. All monsters have their own special abilities, a different amount of creatures and their unique starting deck of cards. The game supports local and online co-op!

In your turn, use your cards one at a time to perform actions. The order of the icons on a card is not mandatory, and you may split actions between multiple monsters you have in play. At the end of your turn, refill your hand back to five cards.

As the game progresses, you will be able to craft loot cards and improve your deck.

Players take turns controlling their monsters on the dungeon. Each monster has a different role to play, some are crowd-control, others can be defensive or supporters, figuring out these combinations and solving an evolving puzzle together can be a lot of fun.

After a player finishes their turn, heroes will invade our dungeon and attack us! Monsters may die, which is tragic, but you can always bring them back to the dungeon! So you are never eliminated from the game, however, a treasure stolen, is gone forever.

If at any point of the game we lose our vault’s hoard, the game ends in defeat, but if we manage to protect our treasures for long enough, we all win.

Each of the levels has a different dungeon layout along with special rules & cards to spice things up! From introductory scenarios where Olga the witch needs frogs to make potions, to more wild ones like the battle of the bands.

Luís Brueh, founder of Brueh Games, said today: “When I launched the tabletop version of Keep the Heroes Out. The response was phenomenal. The board game community thoroughly embraced it, but there was one question that kept popping up: ‘will there be a digital version? Well now there is, allowing players to play with their friends remotely or embark on skirmishes against an AI opponent. We appreciate our community for Kickstarting this version and eagerly spreading the word about it. We couldn’t have done it without you all!”
