“As we’ve come to expect from Handelabra, the digital version is flawless.” - David Neumann, StatelyPlay.com “One Deck Dungeon offers a wealth of strategic gameplay.” - Christian Valentin, AppSpy.com “A surprisingly deep dungeon crawler with vital decisions to be made at every turn.” - PixelatedCardboard.com =============================== 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. Learn more at AeonsEndDigital.com! 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! More content is available via In App Purchase: The Forest of Shadows expansion doubles the content in the game. It features adventures in all-new lush yet deadly locales. A vast network of mossy underground tunnels and connected forest areas await your heroes! Play in 5 new dungeons with 5 new heroes, a new encounter deck, & more! The Abyssal Depths expansion adds a new kind of threat: 6 different Fiends who hound you throughout your entire quest to reach the boss. 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. Choose from 12 powerful relics to take along in your quest, each with unique abilities and mechanics. Play in 5 new dungeons with 6 new heroes, a new encounter deck, & more! Individual expansion cards: • 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. All cards in One Deck Dungeon have many colorful boxes. Roll your dice, and attempt to fill in as many boxes as possible. For every one you don't fill, you’ll suffer consequences in hearts and time! Once you complete an encounter you'll be able to learn a new skill, acquire a new item, or gain experience to level up your hero. Welcome to the world of One Deck Dungeon. Adventure awaits! One Deck Dungeon is an officially licensed product of “One Deck Dungeon” from Asmadi Games. For more information on One Deck Dungeon, check out OneDeckDigital.com
