Xenon Protocol

Co-op card roguelite

Xenon Protocol is an online cooperative roguelite card game for PC, set after a nuclear apocalypse in 2030. You and your team travel through time and space to recover fragments of the Xenon Protocol, which could undo the disaster. Each run is an expedition to nuclear sites, with card plays that must be coordinated in the correct order.

Timing and communication

The team’s only way to communicate is through a tablet powered by gravitational energy. Its signal becomes more distorted as players’ timelines drift farther apart, so information can turn uncertain even when you’re trying to make a simple plan. You have to use that limited signal to synchronize card plays and rely on your teammates’ timing and judgment. Playing cards in the wrong order can make a round fail.
