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.

Frequently asked questions

Steam lets publishers create keys to sell in other shops. Once you activate a key, the game is yours to keep, just like a store purchase.

Disclaimer: CD keys have an inherent 1–2% average failure rate. Check the shop terms for buyer protection info. Steam offers no buyer protection for keys bought in other shops and doesn't refund them.
