About Quantum Protocol
Quantum Protocol is a card game in which you build and change your deck as you play. You take on scenarios ranging from quick puzzles to long tests of endurance, planning your approach as carefully as you execute it.
Adapt your deck
You can change your deck at any time to respond to a situation, but enemies adapt as well. Cards serve as hacking tools, and the range of cards means runs can differ from one another.
The people behind the code
The story follows the lives of people behind the code as an unstoppable computer virus threatens to destroy the modern world. Alongside the global threat, the game explores personal problems hidden within each of them.
