01
Play the lowest card
Across every player's hand, the lowest card goes into the portal next. Nobody can see what the others are holding. Play in the correct order — or fail together.
Perfect order. Total silence.
A co-op roguelite card game where timing and trust replace communication. Play cards in the correct order — or fail.

The game
Undo the nuclear apocalypse of 2030
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. The only way to talk to each other is a tablet powered by gravitational energy. It works fine — until your timelines drift too far apart.

How it plays
Synchronization, intuition and trust
02
No voice. No chat. Only drawings.
Each player lives in a different year. Sketch a hint on your tablet and send it through time — but the farther apart your timelines, the more distorted the signal becomes, turning even simple information into uncertainty.
03
Real places, real history
Travel to more than 100 real nuclear facilities — from Hanford to Sellafield — with authentic locations and coordinates. Declassify each site to open its file: archive photos, key dates and the true history behind it.
04
Countless items, permanent upgrades
Spend quantum in the shop on items that bend the rules — reveal another player's card, shield the team from a mistake, discard whole sets of numbers. Then grow stronger between runs with the skill tree.
05
Survive the boss levels
Every boss changes the rules. Timeout Protocol gives you 60 seconds to finish the round. Man in the Middle makes played cards unreadable. Adapt fast, or the run is over.
