Our take on Quantum Protocol

The bounce point arrives when a quick card play is not enough: enemy adaptation and scenario length demand deliberate planning before execution. Players who prefer fixed decks or short, predictable encounters may hit that wall once deck changes become central to progressing through tougher situations.

What is Quantum Protocol?

Quantum Protocol is a deckbuilding card game centered on hackers confronting malware through a series of scenarios.

Players expand and modify a deck during play, selecting cards as tools for disrupting enemy systems and responding to changing threats. Scenarios vary in structure: some present brief puzzles, while others require sustained planning and execution. Enemies also adapt, so a successful approach may need to change during a run. Alongside the strategic card play, the game presents stories about the people connected to the code, set against a virus threatening the modern world. The game supports multiple approaches, with card choices shaping how each run unfolds.

How Quantum Protocol plays

01Adaptive deckbuilding
Cards can be changed during a run to respond to different situations and enemy behavior.
02Varied scenarios
Challenges include both short puzzles and longer tests built around sustained planning.
03Hacking card toolkit
The deck represents tools for disrupting opposing systems, with card selections varying between runs.
04Character-focused story
Narrative sections explore the lives of people connected to the code during a global virus threat.

Quantum Protocol compared to similar games

Shogun Showdown also combines turn-based combat with deck or ability building, but it centers on positioning, attack tiles, and timed combos against the Shogun. Quantum Protocol instead uses hacking-themed cards, adaptable decks, malware scenarios, and stories about people behind the code.
