Ration is a high-stakes social deduction survival game where the crew of a spaceship, stranded on the uninhabitable Obsidian Moon after a mutiny, must race to reassemble a radio and signal for rescue before the end of the seventh day.

While the Loyal Crew navigates extreme resource scarcity, requiring them to manage food supplies daily to avoid permanent elimination, a hidden faction of Mutineers works from the shadows to sabotage components and stall progress until their own reinforcements arrive to wipe out the survivors.

Through a tense daily cycle of ration distribution, deceptive trading where players can lie about the cards they exchange, and strategic item usage, the crew must manage their dwindling numbers and outmanoeuvre the mutineers before they succumb to starvation or the ticking clock.
