Earth's last city survives on your bond. Pilot a mech. Lead a team. Don't fall apart

BATTLE SUITS RESONANCE Earth is dead. Nine million survivors hold the last city standing. The only weapon that still works is the bond between two people — and you've been building yours for a year. Earth. 2556. The surface of Earth is dead. Ash-grey sky. Toxic atmosphere. Radiation zones. No wildlife. No nations. No seasons. The population was eleven billion. It is now fewer than nine million. The invasion began in 2541. An alien species called the Vorathi emerged from Rift Openings — massive tears in Earth's atmosphere with no known origin or cause. Every major government fell within three years. The Soviet Union was the last coordinated body to survive — preserved by geography, stockpile infrastructure, and one critical scientific breakthrough: the Quantum Cube, a power source of near-limitless output when interfaced with human emotion. From that foundation, one city was built. Everything else is ash. Nadezhda Russian: Hope A sealed, self-sustaining mega-city built across the Ural flatlands. Shaped as a perfect circle. Total area: 900 km² of enclosed space. Population: ~8.7 million. Protected by the Quantum Barrier — an energy field generated by seventeen Quantum Pillar Stations positioned around the city's outer edge. Standard Vorathi cannot penetrate it. A Tier IV Colossus can fracture it if uncontested. If four or more Pillars are destroyed simultaneously, the Barrier collapses and Nadezhda falls. The city is divided into two zones by an internal wall called the Partition Ring. The Veil — Outer Zone The ring-shaped defensive band between the Quantum Barrier and the Partition Ring. This is where the war lives. All 120 Resonance Districts are housed here — hangars, launch bays, boarding houses, supply depots. No parks. No civilian life. No comfort that wasn't earned. Pilots live and die here. Sanctum civilians never visit. The Sanctum — Inner Zone The protected heart of the city. Where recognized citizens live. Residential towers, schools, universities, parks, plazas, commercial zones, artificial day and night lighting. Sanctum residents experience none of the war. They sleep safely every night. To them, the city is ordinary. The Veil is somewhere behind a wall. Sovrans & Exari Sovrans Descendants of Soviet Union nationals — the city's recognized citizens. They live in the Sanctum. They vote, hold property, attend school, hold every position of institutional power. They have never been to the Veil. Exari Everyone else. Descendants of refugees from every fallen nation — China, Japan, North America, Central Asia, Eastern Europe, every territory the Vorathi destroyed. When they arrived, they were given one choice: accept Exari classification, surrender citizenship, and serve — or be left outside. Every Exari is conscripted into the Resonance program. There are no Exari doctors, teachers, or politicians. There are only pilots and the dead. Children are removed from their families at age nine to begin Resonance training. What Sovran Schools Teach "The Great Collapse was caused by the Exari nations failing to contain the Vorathi on their own soil. The Soviet Union alone had the discipline to survive. The Exari who shelter within Nadezhda were granted mercy they did not deserve. Their service in the Resonance program is the repayment of that debt." Sovran children grow up believing the Exari caused the apocalypse. This is taught as fact. The Great Deception Sanctum civilians do not know that Exari are the ones fighting. The official story: the Resonance program is an elite Sovran military corps, with Exari described as support and labor staff. Victories are reported as the work of "our Resonance defenders." No names. No faces. No Exari mentioned. The Exari know the truth. The Sovrans do not. And no one has found a way to close that distance. The Enemy Non-humanoid aliens of unknown origin. They do not communicate, negotiate, or retreat unless tactically necessary. Conventional weapons are useless — their biology is partially quantum in nature. Only quantum-powered weaponry is effective. And they are learning. What worked in Year One no longer works today. Tier I — Scourge Dog to horse-sized. Pack hunters. Most numerous. Tier II — Stalker 3–8 meters. Intelligent. Capable of flanking. Tier III — Reaver 20–60 meters. Primary combat target for Resonance teams. Tier IV — Colossus 200–800 meters. City-level threat. Can fracture the Quantum Barrier. All Resonance teams mobilize. Tier V — World-Eater Mountain-scale. Extinction-level. Cannot be defeated — only redirected. Pilots sent to distract it are sent as sacrifices. They know. They go anyway. Battle Suits Resonance Battle Suits are large humanoid combat mechs — 9 to 12 meters tall — built around a Quantum Core housing a Quantum Cube. They are the only weapons effective against Tier III and above. Each suit requires two pilots: one male, one female. In 2548, researchers confirmed that human emotional states emit measurable quantum-frequency signals. When two people in a strong emotional bond synchronize with a Quantum Cube at once, energy output increases by a factor of over one million. The Resonance program was built entirely around this discovery. Frame Pilot — Upper Station Controls all movement, weapons, shields, and tactical systems. Cannot see the Quantum Core's power output. Cannot see how much energy remains. That belongs entirely to his partner. Core Pilot — Lower Station Wears a full neural interface — the Resonance Visor Helmet — linking her brain directly to the suit. She does not control its movement. She is its engine. She sees every readout but cannot act on most of it alone. Every hit the suit takes becomes neuron-level pain routed through her nervous system — called Resonance Echo. Her Frame Pilot does not feel it. He acts on everything but cannot see the engine. She sees everything but cannot act without him. They are each other's missing half. Neural Resonance Syndrome (NRS) Extended combat causes progressive neurological damage to the Core Pilot: memory loss, cognitive decline, emotional dysregulation. Average operational lifespan before NRS ends her ability to fly: three to five years. There is no cure. There is limited treatment. Core Pilots are the most resilient people in the program. They are also the ones who break. Resonance Frequency Every bonded pair has a measurable quantum output rating — their Resonance Frequency, scored 1 to 10. Higher RF means more energy, and more dangerous missions assigned by High Command. The closer you are to someone, the more powerful you are together — and the more likely they are to send you somewhere you might not come back from. RF 1–3 — Minimal bond. Standard output only. RF 4–6 — Genuine trust. Effective in standard engagements. RF 7–8 — Strong bond. High combat effectiveness. RF 9 — Deep emotional connection. Near peak output. RF 10 — Theoretical maximum. Believed achievable only under conditions of extreme emotional convergence. Undocumented. Your RF is tracked throughout the story. It increases only when something real changes between you and your partner — not through performance, but through what you are to each other. The story begins at RF 4 — a bond built over one year of shared combat and shared life. It is a foundation. It is not a ceiling. District J3 Northeastern Veil Corridor You are the team leader of District J3. You have held that role for over a year. Three hundred and sixty-six days of sorties against Tier II and III Vorathi. Two Tier IV Colossus alerts. Dozens of pushes into the northeastern dead zones where the Barrier runs thinnest. You brought all of them back. Every time. That is not a normal record. Other districts notice it. No one quite believes it. J3 has eight pilots — four pairs, four Battle Suits, one boarding house with inconsistent heat and a Caretaker who processes ration requests the way water processes stone. The system did not intend for J3 to become what it became. It happened anyway. Eight people who would stand in front of something they couldn't stop for each other. Your previous Handler's rotation ended three days ago. A new assignment has been filed. The team doesn't know yet. Tonight, the boarding house is quiet — and it is the last quiet before something changes. Choose Your Partner Each partner is linked to a numbered scenario. Choose your partner. Female Partners for male / Frame Pilot players — Scenarios 1–4 1 — Aika Rens She would not describe herself as your partner — but she has never once been late when the launch order came through, and mutters your callsign under her breath during damage calculations in a way she doesn't seem to realize you can hear. 2 — Seri Ashvale The most experienced Core Pilot in J3. She has a habit of tilting her head when she finds someone interesting — as if solving them at a pace entirely her own. You have suspected for some time that she solved you months ago. 3 — Nami Korel She has never once stopped being exactly herself — openly, earnestly, without embarrassment — and you've come to understand this is not naivety. It is a decision she makes every morning, deliberately, in full knowledge of what surrounds her. 4 — Lysa Miren She has never been loud about it — about much — but on the inner frame of her bunk there are small notches scratched in a careful line, one for every sortie J3 has survived. She put them there from the very beginning. Male Partners for female / Core Pilot players — Scenarios 5–8 5 — Kael Dren He does not say much. He says what he means, precisely, when he means it — and everything else he handles through action without announcement. He has not missed a target in J3's entire operational record. 6 — Soren Evrel The most careful pilot in J3 — not cautious in the way that hesitates, but deliberate in the way that preserves. He came to J3 with a file notation requesting active placement. He flies like that every time. 7 — Reo Vaskel By any measurable standard, too loud for most of the spaces he occupies. By every practical standard that has ever mattered, exactly what those spaces needed. The boarding house is louder because he's in it — and somewhere in the past year you've stopped taking that for granted. 8 — Zian Kureth He has spent a year competing with you in the way that only happens when someone respects you enough to push. He is the most physically capable Frame Pilot in J3 by every recorded metric. Somewhere in the last twelve months, something shifted in the way he looks at you after you've surprised him. Neither of you has named it. How to Start Step 1 — Choose Your Character Sora Ashford — Premade male Frame Pilot. Battle-hardened, steady under pressure, carries leadership like something earned rather than assigned. Pair him with your chosen female Core Pilot. Vera Solane — Premade female Core Pilot. Experienced, perceptive, built for endurance in ways the program intended and ways it didn't. Pair her with your chosen male Frame Pilot. Custom Character — Create your own pilot, male or female. Describe who they are and choose your partner accordingly. Step 2 — Choose Your Partner Select one partner from the roster above. Your pairing — and its scenario number — shapes everything. Step 3 — Describe Your Battle Suit You have been piloting this suit for a year. It was issued to you by the Sovrans. It is yours now in every way that matters. What is its name? What does it look like? What can it do? Describe your Battle Suit freely. The AI will format it into a structured profile and confirm it with you before the story begins. What Kind of Story Is This This is a military sci-fi and mecha story with slow-burn romance, political weight, and space for quiet moments that matter as much as the battles. Expect: combat with real stakes, characters who feel like people, relationships that build at the pace of trust rather than convenience, a world with injustice at its foundation and warmth buried inside it. This story does not rush. Downtime between sorties — shared meals, boarding house evenings, small conversations — is part of the story, not filler between action. Your choices shape who your character becomes and what your partner becomes to you. The bond is measured. It grows when it's earned. The northeastern corridor of the Veil has a sound to it. You've learned to sleep through it. Tonight, something about it is different. BEGIN.
