Indie developer Desu Kumiai has today (October 17, 2025) released a limited-time demo of their new PC game, The Hero Party Has Been Annihilated, on Steam. The demo will be available until November 2.
This game is a roguelite-style dungeon exploration adventure in which players must select just one member from a hero party trapped deep within a dungeon and work together to escape.
Players take on the role of the last surviving member of a rescue team, discovering the hero party deep in the dungeon. However, all members are in abnormal states: the hero can only say “yes” or “no,” the wizard cannot use magic, the warrior has turned into a cute doll, and the priest worships an evil god.
Saving everyone is impossible—players must make the cruel decision to choose just one survivor.
Within the labyrinth, multiple paths are available. Players can choose to avoid battles and conserve resources or deliberately fight to gain experience points.
Combat is turn-based card battle with timing mechanics—players must press buttons at the right moment when a gauge fills up while using weapons. Weapons wear down over time, but some unleash special effects precisely at the moment of breaking.
Additionally, during exploration, conversations with chosen companions may occur. Depending on your choices, relationships and dialogue will change—and can even influence the story’s ending.

About The Hero Party Has Been Annihilated
The Hero Party Has Been Annihilated is a roguelite-style dungeon exploration adventure where you select just one survivor from a hero party trapped at the heart of a dungeon and escape together.
You are the last remaining member of the rescue team, tasked with saving the party. But upon finally finding them, something feels off about each member.
The hero can only say “yes” or “no,”
the wizard cannot cast spells,
the warrior has turned into a cute doll, and
the priest worships an evil god…
With such uniquely flawed characters, saving everyone is impossible! So you must choose just one to survive—and together, escape the dungeon.
A Story Crafted with “Flawed” Hero Party Members
During adventures, conversations may occur with the character you’ve chosen as a companion. Your decisions will affect their relationships and change what they say.
Some choices might even alter the story’s ending. Witness an adventure told across approximately 200,000 characters of text.
A Roguelite-Style Dungeon Adventure with Life-and-Death Stakes
The dungeon branches into multiple routes. You can avoid monsters to preserve stamina and weapons—or intentionally engage in combat to gain experience points.
Whether you take risks for higher rewards or follow the safest-looking path depends on your strategy—and that choice shapes the adventure itself.
A Unique Card Battle Where Timing Matters (Literally?)
Combat is a turn-based card battle, alternating between your side and the enemy. However, using weapons requires watching a gauge and pressing buttons at just the right moment.
Weapons wear down with each use, so you must think carefully about when and which weapon to use—searching for the optimal strategy.
Additionally, when a weapon breaks, it often delivers increased damage or healing power at that moment. Some weapons even trigger special effects upon breaking. Mastering how to make full use of your gear is key to victory.
