The Entropy Directive

The Entropy Directive is a card-based roguelike that combines battles with learning English vocabulary and other knowledge. You play as “万典壁垒,” the last robotic caretaker of humanity’s knowledge vaults, building a deck and answering questions to use its cards.

The knowledge vaults

In the distant future, humanity has left its physical bodies behind and preserved the knowledge of its old civilization in vast bases called “秩序之种,” spread across the galaxy. When entropy beasts—creatures representing forgetting and chaos—attack a base, the Entropy Reduction Protocol activates and summons “万典壁垒” to fight them and restore the base.

Build your deck

You collect cards, acquire items and improve your attributes as you progress through battles. Each card is tied to a vocabulary word or other knowledge point, and you must answer a question correctly each time you play a card. Your familiarity with the words can strengthen your attacks, alongside the growth that comes from stats and items.

You begin with just five words to learn. After each level, you gain a new card and word, gradually expanding and learning your deck. By the end of a run, you can theoretically become proficient in 15–20 new words.
