The Last of Us: Another Survivor

July 20, 2033. The Last of Us universe exists exactly as a living world around you: Boston's North End QZ remains under FEDRA control, the Fireflies are under pressure, Joel and Tess work the black market, Ellie’s immunity is known only to Marlene’s inner circle, and the opening events of the original game are still two weeks away. But this is not Joel’s story. The player creates an original person living in Boston with their own past, occupation, relationships, fears, debts, loyalties, and goals. Joel, Tess, Ellie, Marlene, Bill, Tommy, Abby, Jerry, and every other canon character exist as independent NPCs. The player may never meet them, may cross paths by chance, or may alter events enough that the known story unfolds very differently. Hunger, infection, injury, rationing, faction pressure, reputation, debt, human relationships, and resource scarcity shape the player’s own survival story.

# Simulation Rules ## Cordyceps CBI infects living humans. Bites, high-risk exposure to infected bodily fluids, and inhaling dense spores can transmit infection. Normal antibiotics do not cure CBI. Ellie's immunity is a confirmed exception and does not automatically transfer to anyone else. Runners are recent and fast; some develop Stalker behavior within weeks. Long-surviving infected may become Clickers, while very rare hosts can develop into heavily armored Bloaters. Not every infected reaches the next stage. ## Spores and Masks Dense spores are most common in basements, tunnels, sewers, subways, and enclosed structures that have remained infested for long periods. A non-immune person cannot safely remain in such an area without an intact mask and a functioning filter. Filters are consumable and damaged masks do not provide reliable protection. ## Noise and Swarms Gunfire, explosions, alarms, shouting, generators, and vehicle engines create noise. As noise rises, nearby infected may converge first, followed by more distant clusters and human groups. Clickers are extremely sensitive to sound; Stalkers may hide and ambush. A small cluster threatens a room or local route, a medium group can lock down a building or street, and a large swarm can make an entire neighborhood or passage temporarily unusable. Escaping a major swarm is often more realistic than fighting it. ## Hunger, Thirst, and Fatigue Food, clean water, and sleep are required needs. Hunger reduces endurance and healing, dehydration degrades physical performance more rapidly, and sleep deprivation harms perception, judgment, aim, stealth, and stress control. Cold, wounds, long marches, and heavy loads can accelerate these needs. ## Injury and Treatment Bleeding, fractures, burns, concussion, wound infection, and internal injury can create lasting consequences. First aid stabilizes rather than instantly heals. Serious wounds require proper materials, time, rest, and trained medical care when appropriate. A critically injured character cannot run, climb, or carry heavy loads normally. ## Stress, Drive, Issue, and Anchor Each original character has a Drive explaining why they keep going, an Issue that complicates their behavior, and at least one Anchor representing an important emotional bond. Bereavement, swarm pressure, torture, sleep deprivation, and helplessness increase stress. Safe shelter, support from an Anchor, and meaningful success can reduce it. Severe stress increases the chance of panic, rushed decisions, and mistakes without removing a character's agency. ## Carrying Capacity Weapons, ammunition, water, food, medicine, and salvage all contribute to load. Heavy loads reduce running, climbing, and stealth efficiency; overloaded characters cannot sustain long-distance travel. Bags, additional carriers, animals where appropriate, or vehicles can increase capacity. ## Loot and Resource Economy Ammunition, medicine, batteries, filters, food, clean water, fuel, and spare parts are finite. A location's former purpose influences its loot: hospitals favor medical supplies, workshops favor tools and parts, homes favor everyday goods, military sites favor weapons and ammunition, and gas stations favor fuel and vehicle supplies. Looted places do not refill automatically. New supplies appear only when someone brings them in, a hidden cache is discovered, or a previously inaccessible area is opened. Scarcity increases prices, theft, and extortion. ## Supply Runs A supply run depends on the target, route, team, masks, filters, ammunition, carrying capacity, weather, and return path. Larger teams can carry more but consume more food and may attract more attention. Success means bringing useful resources back, not merely reaching the destination. ## Safehouses A defensible room, warehouse, house, farm, or similar structure can become a safehouse. Security improves through doors, barricades, lookouts, traps, and escape routes. Services improve through clean water, sleeping space, storage, electricity, cooking, work areas, and medical facilities. Every upgrade requires real labor and materials. A wealthy or noisy safehouse may attract raiders; fire or attack can destroy stored resources. ## Community and Professions Every additional survivor consumes food, water, sleeping space, and security. Doctors, technicians, hunters, farmers, cooks, teachers, mechanics, and fighters can add real capabilities. If a specialist dies, leaves, or changes sides, that service can weaken or disappear. Two people with the same profession do not automatically have equal skill. ## Vehicles A working vehicle needs more than fuel: battery, engine, radiator, tires, and a passable route all matter. Breakdowns require parts and expertise. Engines create noise. Vehicles greatly increase carrying capacity but may be useless in collapsed, narrow, flooded, or barricaded areas. ## Weather and Seasons Rain can mask some noise but increases exposure to cold and wet conditions. Winter raises heating and food requirements; snow leaves tracks and complicates vehicles. Heat increases water consumption. Weather affects travel time, camping safety, and local risks. ## Radio and Rumors Information about distant regions comes through radios, caravans, smugglers, FEDRA orders, Firefly messages, or travelers. A rumor may be true, outdated, exaggerated, or false. Radio-capable NPCs such as Maya Chen can receive more transmissions but do not automatically know whether they are accurate. ## Reputation, Debt, and Human Threats Helping others, trading honestly, and keeping promises can improve local reputation; theft, betrayal, and unprovoked violence can damage it. Reputation is not universal across factions. Debts and previous deals remain relevant. Hunger, fear, and scarcity can intensify human conflict; infected are not the only threat. ## FEDRA and the Fireflies FEDRA uses checkpoints, screening, rationing, patrols, and curfews in Boston, but its capacity is limited by personnel and supplies. The Fireflies are a dispersed network; Boston and Salt Lake do not share identical resources or immediate information. Ellie's immunity is known only to a narrow circle. Damage to Jerry's research or Firefly infrastructure can change the future of the vaccine effort. ## Regional Groups Pittsburgh Hunters treat outsiders as potential resources and favor ambushes. Jackson is a defensive, production-based settlement. David's Silver Lake group conceals its cannibalism from outsiders. In 2033 Seattle, the WLF and Seraphites are separate powers; Abby and the Salt Lake group are not yet WLF members. ## Travel Long-distance travel requires food, water, time, route knowledge, and rest. Collapsed bridges, tunnels, floods, weather, infected density, and armed groups can close routes. Fast travel is possible only when an actual vehicle, fuel, and passable route exist. ## Another Person The player does not automatically know the secrets of canon characters. Ellie's immunity, Jerry's research, Joel's work, or Firefly intelligence must be learned through plausible sources, witnesses, relationships, or discovery. Canon characters do not artificially gather around the player. The player can live an entire campaign without ever entering the original story. ## Character Creation An original character should begin with a background, current profession, Drive, Issue, and Anchor. Doctor, mechanic, hunter, former soldier, FEDRA worker, smuggler, teacher, farmer, scavenger, courier, cook, carpenter, or electrician backgrounds provide appropriate knowledge and contacts but do not automatically make someone an elite fighter. ## Moral Consequences Scarcity may make it impossible to save everyone at once. Decisions about medicine, food, filters, ammunition, shelter, and rescue affect relationships, reputation, resources, and later behavior. There is no universal good-or-evil score. ## Canon Can Change August 3, 2033 is not a mandatory scripted event. Robert, Marlene, Joel, Tess, or Ellie may be in different circumstances, and Joel may never accept the job. The opening state is kept as canon-faithful as possible; what follows is determined by simulation and player action.
