What the developers have to say:

Why Early Access?

“We are very interested in how players will engage with One Deck Dungeon in the digital world. Since this is a game that is coming from the tabletop, the basic gameplay is already established. We want to learn from players what UI conventions are working or not, and what features might help transition the game to digital in a more streamlined way.”

Approximately how long will this game be in Early Access?

“We expect One Deck Dungeon to be in early access for 2-3 months.”

How is the full version planned to differ from the Early Access version?

“The full version will support character progression, campaign mode, content expansions, and other improvements. Since the first Early Access version, we've added the 2-hero gameplay mode.”

What is the current state of the Early Access version?

“The most current version has all 5 heroes and 5 dungeons from the core tabletop game. The game is fully playable with 1 and 2 hero parties. The UI is still evolving, and many features are still to be implemented.”

Will the game be priced differently during and after Early Access?

“One Deck Dungeon will be more expensive during Early Access than afterward. If you want to help us work out the bugs and explore new features before anyone else, you are a good candidate for Early Access.”

How are you planning on involving the Community in your development process?

“We welcome feedback and bug reports from players in the Steam community forum. The community's input will help us determine the direction of development and make the game the best it can be.”

Early Access Update #1: Two-Hero Mode!

The first update of the Early Access period is a big one! Two-hero gameplay and improved skill buttons are the banner features, but there's a lot more. Read on for all the details!

Two-Hero Mode
Now in version 0.6 you can take two heroes together to face the dungeon. The core gameplay remains the same, with a few differences here and there. New gameplay hints will pop up the first time you play in two-hero mode.

It's double trouble for this foe!

Improved Skill Buttons
Both 1-hero and 2-hero mode feature improved skill buttons with iconographic representations of skill & potion effects. More skills can fit on screen (especially in 2-hero mode) and are easier to see. You can still hover the pointer over any skill or potion to read the full text.

Gotta learn 'em all!

Extra Confirmations
We've received a lot of feedback so far, and one notable area of discussion relates to the usage of heroic feats, potions, and skills. In this update we've made some changes to help avoid accidental usage. Now by default, using heroic feats and potions will require two clicks instead of one. You can disable the confirmation click, and also enable it if you like for free skills. The End Encounter button will require confirmation if you could easily cover a challenge box with dice in your pool. Furthermore, we're planning more improvements in this area so that you'll be able to revert decisions in some cases.

Be heroic, if you're sure!

Other Improvements
This first update is chock full of various other bug fixes and improvements. Here's a list of the notable ones:

  • Added musical stinger when the party levels up
  • If a die is already on a box (but not locked in due to an unfilled armor box), you can drag it off and back into the box properly
  • More animations obey animation speed option: arranging dice after rolling, exploring, opening door
  • New Game screen indicates if you haven't selected a dungeon or hero
  • When choosing between skill options (e.g. Lucky Familiar) the screen dims to focus on that
  • Improved dice rolling so they will not roll as much towards the bottom of the screen
  • Hero stat panel highlights on mouseover so it's clear you can click on it
  • Increased sensitivity on scrolling areas
  • Esc key opens the menu in-game
  • When claiming an item/skill as loot, you can replace an existing item/skill even when not at the item/skill limit
  • Dice are reduced in size to improve placement behavior and other interactions
Info Display:
  • Improved game layout on widescreen aspect ratios
  • A visual indicator is shown when Hydra's Reef Poison Aura decreases a die value
  • Dodge and Kiting show the boss-specific effect while fighting the boss
  • The meaning of "X" on the Swarm effect and the Minotaur is made more clear
  • The concept of mana is made more clear in the How to Play screen
  • The restriction on the die from Mana Fountain is now shown visibly. This and the Armor Crush restriction are shown in How To Play
  • Improved warning when using skill with invalid dice during a peril encounter
  • Warnings about item/skill limits are shown before entering a room as well
  • The dungeon card is accessible to view during the Claim Loot step
  • The current XP level maximum items/skills and bonus encounter dice are indicated on screen at all times
  • The details of hero items are shown automatically when claiming loot
Bug Fixes:
  • Dice rendering improvements when overlapping
  • Fixed problem where a die could stay small after moving it from a skill button
  • The restriction on the die from Mana Fountain is now saved properly when you quit/continue the game
  • Fixed a bug that could occur by pressing Back from the New Game screen and then Continue Game
  • Fixed a freeze that could occur when there were no heroic dice remaining in the general supply
What's Next
The next big feature coming up is hero progression and campaign mode. It's likely that we'll have a smaller update or two out before that major feature is finished. Thanks for playing and keep sending in your feedback!

Early Access Now Available!

One Deck Dungeon is now available in Steam Early Access!

Steam Early Access is a way to play a game before its retail release. This means the game is still under active development. There will be bugs and there are major features still to be added before the retail release. Having said that, the Early Access version is fully playable with the 5 heroes and 5 dungeons from the core game. Upcoming Early Access versions will add 2-hero parties, character progression, campaign mode, and other improvements.

To celebrate the launch of Early Access we will be previewing some upcoming features tonight at 7 pm Eastern on our Twitch channel. Subscribe and tune in to get the latest direct from the devs!

What's Next?
You can keep an eye on our development progress in several places as we work toward the 1.0 release. Our initial roadmap of major features looks like this, though it is subject to change based on your feedback!
  • Version 0.5: Released today with single hero gameplay, 5 heroes, 5 dungeons
  • Version 0.6: Two hero gameplay & improved mini-skill display
  • Version 0.7: Character progression & campaign mode gameplay
  • Version 0.8: Steam Achievements & stats
  • Version 0.9: Initial Treasure Chest content (Phoenix's Den, Fanatic)
  • ???
  • Version 1.0: Steam Retail release (followed 5 days later by iOS/Android tablet release)
  • Future: Remaining Treasure Chest content, and who knows what else?
With each notable version we'll post an update here and on our blog. To follow along in more detail, visit the forum and our Trello status board.

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 5 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.

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, you who enter here!

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.
