About This Game

A co-op roguelite card game where timing and trust replaces standard communication. Play cards in the correct order or fail.

Recover the fragments of the Xenon Protocol held in real-world nuclear sites.

Coordinate through a signal that breaks down across time and use peculiar items acquired between rounds.

Save the future without saying a word.

Xenon Protocol is an online cooperative roguelite card game built around synchronization, intuition, and trust. Your team travels through time and space to recover the missing fragments of the Xenon Protocol—the last chance to undo the nuclear apocalypse of 2030.

Every expedition takes you to real nuclear facilities with authentic locations and coordinates.

What makes it different?

The only way to communicate is through a gravitational energy-powered tablet. It works fine until your timelines drift too much apart. The greater the temporal distance between players, the more distorted the signal becomes, turning even simple information into uncertainty.

Warning: AIs are protecting some sites! 

Confront boss levels that make completing rounds even tougher. Race against time, dodge lethal security systems, and much more.

Every run changes

• Coordinate card plays with almost no communication.

• Find several powerful items that reshape your team's strategy and help clear difficult rounds.

• Defeat bosses guarding Xenon fragments.

• Unlock permanent upgrades that carry over between runs.

• Visit over 100 real-world nuclear sites across different points in time.
