Evaluation

One Deck Dungeon launched on May 18, 2018 and received a steady stream of content through its first two years. The developer shipped several hero and dungeon DLCs in mid-2018, followed by the Forest of Shadows expansion (August 1, 2018) which doubled the game's content, and finally the Abyssal Depths expansion on October 28, 2020 — the last major content release. All 9 DLC items listed on the store are released; none are pending. Since Abyssal Depths shipped in October 2020, the developer has continued to maintain the game with engine updates, platform optimizations (Steam Deck support in March 2022), and occasional bug fixes — the most recent being a security patch on October 7, 2025. However, none of these post-2020 updates have introduced new game content, and the developer has made no announcements about additional expansions, heroes, or dungeons. The last of the six major content releases identified across 39 news posts was Abyssal Depths in 2020, and the pattern of major content releases clearly ended there. With all DLC shipped, no unannounced or unreleased content visible on the store, and no developer communication indicating future content plans, the game's content appears complete as of October 28, 2020. Ongoing patches since that date reflect continued technical stewardship of a finished product rather than active content development.

About this game

Adventure calls... but you don't always have time to spend hours optimizing your character sheet or managing your inventory! One Deck Dungeon lets you jump right in to bashing down doors, rolling dice, and squashing baddies with style. Get a full roguelike game experience, boiled down to its essence, and captured in a single deck of cards and a handful of dice!

One Deck Dungeon is a dungeon crawling adventure game for one or two players. Each time you play, choose one or two of these 6 brave heroes:

  • Mage - There's rarely a problem in the dungeon she can't solve with a spell.

  • Warrior - Her favorite dungeon activity is squashing her opponents immediately.

  • Rogue - Watch in awe as she dispatches monsters with style.

  • Archer - Accurate, brilliant, catastrophically deadly.

  • Paladin - She seeks out danger and shields her allies from deadly enemies.

  • Mist - This breach mage has crossed over from the world of Aeon's End to help defend Mynerva.

After every game, your heroes make progress toward unlocking up to 15 new talents, building up their power for future games.

There are 5 dangerous challenges to face:

  • Dragon’s Cave - The thick-skinned wyvern who occupies this dungeon prefers her heroes on the crispy side.

  • Yeti’s Cavern - If you can survive the freezing winds and biting cold, an abominable snowman awaits.

  • Hydra’s Reef - Chop off one head, and another appears! This regenerating venomous monstrosity is a slippery foe.

  • Lich’s Tomb - Hordes of undead foes, evil curses, and magical wards. What could possibly go wrong?

  • Minotaur’s Maze - Abandon all hope, ye who enter here!

One Deck Dungeon is fully playable with gamepad controllers. We officially support Xbox, PlayStation, and Switch Pro gamepads, but most gamepads should work. The game switches seamlessly between gamepad and mouse depending on what you use.

The Forest of Shadows expansion doubles the content in the game and is available as downloadable content via Steam. It features adventures in all-new lush yet deadly locales. A vast network of mossy underground tunnels and connected forest areas await your heroes!

  • 5 new heroes - Alchemist, Druid, Hunter, Slayer, & Warden

  • 5 new dungeons - Lair of Indrax, The Mudlands, Realm of Venom, Smoldering Ruins, & The Vile Roots

  • A complete new 44-card encounter deck

  • Additional progression focuses, basic skills, potions, & more!

The Abyssal Depths expansion adds a kind of threat: Fiends who hound you throughout your entire quest to reach the boss. It includes 6 different Fiends, each with two levels of difficulty. Plus, 2 new aquatic heroes join the fight in the murky waters!

The all-new Relics of the Forge expansion more than doubles the content in the game and is available as downloadable content via Steam. Choose a powerful relic to take along in your quest, each with unique abilities and mechanics.

  • 6 new heroes - Flamberge, Foxfire, Shade, Smith, Spinner, & Thrasher

  • 5 new dungeons - Arena of Fire, The Armory, Chasm of Soot, Heart of the Forge, & Tropic of Lava

  • 12 mysterious and powerful relics

  • A complete new 44-card encounter deck

  • Additional progression focuses, basic skills, potions, & more!

Individual expansion cards are available as downloadable content via Steam:

  • Caliana - This faerie has decided that dungeoneering looks fun! Don't let her get bored...

  • Fanatic - A righteous Sentinel is here to smite evil wherever it may lurk!

  • Witch - Her chaotic magic hammer is ready to smash glooping oozes into glooping puddles!

  • Cinder Plains - The Hellhound awaits those reckless enough to venture here...

  • Phoenix's Den - Only the bravest heroes can handle the heat!

Once you know your way around the dungeon, a game takes about 15 minutes. It might take a little longer if you're learning, or a lot shorter if you jump into a pit of spikes.

Warning: do not jump into a pit of spikes.

HELLO! Would it be impolite if I were to nom on your armor and weapons? That shiny metal looks oh so delicious. Oh --pardon me, how rude of me not to introduce myself! I am Glooping Ooze, one of the many extremely polite denizens of the dungeons in this area. I even have my own card:

Like all cards in One Deck Dungeon, mine is full of colored boxes, and HEY! What's the idea with all those arrows. Ugh, adventurers. So rude. So very very rude. I suppose you're rolling all your dice, attempting to fill in as many boxes as possible. For every one you don't fill, I'm going to make you pay for this arrow nonsense, in hearts and time! Precious time!

If you manage to get past me somehow, you'll be able to take Armor Crush as a skill, or add that magic icon on the left to your stats, or take the three experience lanterns in the upper-right.

Despite your arrowful attitude, I welcome you to the world of One Deck Dungeon. Adventure awaits!

One Deck Dungeon is an officially licensed product of “One Deck Dungeon” from Asmadi Games.
