Cyber Sword Immortal: The Heavenly Dao Protocol

Cyber Sword Immortal: The Heavenly Dao Protocol is a strategic deck-building roguelike set in a universe where ancient cultivation and advanced technology have become one.

Heaven is no longer an unknowable force. It is a protocol—a system capable of observing your actions, predicting your strategy, and rewriting the rules of battle in real time. To ascend, you must do more than grow stronger. You must expose its weaknesses and turn its own calculations against it.

Build Your Cultivation Deck

Choose from four distinct classes, each with its own cards, resources, mechanics, and tactical identity. Collect new techniques, upgrade key cards, remove inefficient ones, and combine planetary relics to create a powerful combat engine.

Every card matters, but the order in which you play them matters even more.

Cards belong to three combat forms: Attack, Guard, and Momentum. Changing between forms builds toward powerful combinations that can deal additional damage, generate energy, draw cards, strengthen your defenses, or disrupt enemy actions.

Fight Enemies That Adapt

Enemies openly display their intentions—but they are not passive.

They observe the cards you commit and may change their tactics before the round is resolved. An enemy preparing to attack might raise reactive armor. A defensive formation might become an aggressive countermeasure. A carefully arranged sequence, however, can break its protocol and cancel the action entirely.

Your cards and the enemy response resolve together at the end of the round. Victory depends on prediction, misdirection, timing, and resource management—not simply dealing the highest possible damage.

Navigate a Randomized Journey

Each run takes you through a 45-node interplanetary route filled with:

• Standard and elite battles

• Unpredictable events

• Shops and card-removal services

• Rest and recovery opportunities

• Treasures and planetary relics

• Escalating environmental threats

Every choice shapes your deck and determines whether your strategy will survive the next encounter.

Rewrite the Heavenly Dao

Ten difficulty levels steadily increase enemy strength, environmental pressure, and the demands placed on your deck. Study hostile behavior, refine your card sequence, and transform every failed run into a better ascension algorithm.
