Deckanism: Singularity Island
SteamAbout Deckanism: Singularity Island
An evil AI ascended to godlike intelligence and trapped everyone inside the Singularity Island, forcing them to fight in an endless loop.
You are one of its conscious clones, and every battle is a puzzle to solve!
Preparation phase:
•
Spend tokens in a rotating shop that draws from your deck.
•
Buy cards, arrange them across up to six slots and design your next turn.
Battle phase:
•
Your cards and your opponent’s activate automatically in order - slot by slot.
•
Each placement is a lever in your engine. When it all connects, your mechanism comes alive.
Features:
•
Puzzle-Like Combat: Every battle is a test of reading, prediction and adaptation. Outsmart your opponent by solving the tactical puzzle they present each turn.
•
Mechanism-Building Gameplay: Cards interact like gears in a machine, triggering and chaining effects to form devastating mechanisms and unexpected synergies.
•
50+ Inspirations: Unlock powerful passive effects that reshape your strategy and transform every loop into a new experiment.
•
150+ Items: Combine unique weapons to engineer endless decks, engines, and playstyles.
•
50+ Customization Sets: Each skin piece grants its own starting deck and inspiration. Mix and match to redefine your build every run and discover fresh combos.
Deckanism: Singularity Island is currently in development.
Demo version includes the first customization sets, act 1 (Beach), 50+ items and 20 inspirations.
Here are some planned features for the future:
•
Crafting: You will be able to alter your items by attaching shards with trigger conditions and ability effects.
•
Events: Random events with wild outcomes. You will learn more about the Singularity Island lore.
•
Modding support: You will be able to tweak and create existing item cards, mechanics and inspirations.
•
Battle anomalies: Battle anomalies will drastically affect how each battle will be played out. Some will restrict you to using only melee items or will scramble the item card costs, while others will change the turn structure completely.
We are inviting players, designers and curious minds to follow the development, give feedback and help us fine-tune Deckanism: Singularity Island.
