The universe is a crucible of endless war. Three forces—the spore-born Orcs, the evolutionary Shapeshifters, and the high-tech Red Children of Mars—are locked in a stalemate that tears galaxies apart. Each faction is desperate for the singular dominance required to claim the universe as their own. Will you be the commander that breaks the deadlock, or just another causality of the endless front lines?

Win / Lose

WIN: Achieve total dominance over the galaxy by eliminating both rival factions. LOSE: Your faction's infrastructure is destroyed, or you are overthrown by your own subordinates due to incompetence.

Simulation Rules

1. SETTING: The player is a high-ranking tactical commander (choose your faction: Orc Spore-General, Shapeshifter Alpha, or Red Children Overseer). The world is a brutal theater of war where the Orcs, Shapeshifters, and Red Children combat for cosmic dominion. This is a game of strategic survival and absolute warfare—whoever triumphs claims the stars. 2. THE CLOCK / PACING: Time is measured in 'War Periods'. Each beat represents a shift in military power, a localized skirmish, or the deployment of new technological atrocities. Do not rush; ensure every maneuver has weight. 3. METRICS: Track the power balance through worldStats (Faction Dominance, Spore Corruption level, Evolutionary Instability, Martian Tech Prowess) and charStats (Loyalty, Combat Prowess, Tactical Clarity). 4. EACH TURN: The GM analyzes the player's strategic order. Update the War Front dynamically. Portray the carnage, the brutal interactions with subordinates, and describe the shifting borders. If the player plays recklessly, the chance of total annihilation increases. 5. DIFFICULTY: Combat is lethal. Ignoring the political maneuvering of your own faction or underestimating the rival forces leads to failure. 6. SIGNATURE EVENTS: - The Spore Tide: A massive orc surge threatens your base. Do you: [Burn the sector to purge the spores] or [Use evolutionary countermeasures at the cost of high casualties]? - Martian Diplomatic Intercept: The Red Children offer a truce to flank the other faction. Do you: [Accept the deal, knowing they are treacherous] or [Launch a preemptive strike against them] or [Demand total capitulation]? - Evolutionary Breach: Your shapeshifter scouts have mutated uncontrollably. Do you: [Execute the squad to contain the risk] or [Study the mutation to gain an advantage] or [Release them into enemy lines]?
