🧟 OUTBREAK — A Realistic Zombie Survival Mod for The Sims 4

Outbreak turns your sim worlds into a slow-burning apocalypse. No sprinting hordes, no arcade nonsense, just relentless, shambling dread that creeps closer every sim-day. Dangerous, but always fair. Fully standalone, base-game friendly, and built from the ground up with custom animations, custom skins, and deep survival systems.

This is very very early release access, there will be bugs and a lot of features to be added but I work on this mod DAILY, please comment your bugs/ideas/suggestions!

🌒 A World That Falls Apart in Phases

Trigger the collapse yourself and watch society unravel across five escalating stages:

Dormant – life as normal… for now

Rumors – something's wrong. A lone shape in the dark.

Outbreak – the dead walk. People start to turn.

Collapse – the streets belong to them. Careers end. School's out forever.

Endgame – you and yours against what's left

Each phase ramps up spawns, danger, and desperation. Fewer and fewer living NPCs wander by as the world empties out around you. Trigger the outbreak by clicking on your sim and going to the "outbreak" pie menu.

🧟 The Horde — Built for Realism

Slow shamblers that never run — realism is the whole point

Your actual neighbors rise as the dead — the people you knew

They spawn out in the neighborhood and shamble toward you

Roam outdoor spot to outdoor spot across your lot, the street, and neighbor yards

Haunt an area for 4–6 sim-days before drifting on — a real infestation, not a spawn blip

Up to 8–12 zombies around your lot at peak

Dull perception — they sense you ~12m out… but noise carries. Talk in a group near one and the block hears it.

Custom shambling walkstyle, custom idle sway, custom lunge attack, and a custom victim reaction when they grab someone

Red "ZOMBIE" hover title and a gruesome zombie skin

The dead have no autonomy — no phones, no snacks, no chatting

No special NPCs get infected (Grim, Father Winter, mascots, etc)

🦠 Infection & Turning

A bite starts the clock: Bitten → Fever → Delirium → turned. Check a Sim's infection status, and when one of your household finally succumbs, they're lost to the horde — gone, shambling away wearing a face you used to love.

⚔️ Combat — Dangerous but Fair

Encounter chance cards when the dead get close: fight or flee

Weapon-aware odds — your fitness and your best weapon tilt the fight

Fight Off any zombie directly — your Sim walks up and struggles

Injuries from bad rolls: sprains, deep cuts, and rare permanent wounds

⚰️ Corpses — Put Them Down for Good

An armed kill drops a zombie permanently — a custom collapse-and-lie-still animation

Bodies stay where they fall. They don't vanish.

Loot Corpse for simoleons (deeper loot coming)

Set Corpse on Fire — the only way to truly dispose of them. Watch them burn away.

🧍 Survivors — Rare and Precious

Wandering survivors occasionally appear (rarely — every few sim-days at most), marked with a red "SURVIVOR" title

Recruit them: walk over, talk, win them over with a chance card

Recruited survivors join your household and become playable

Kick Out anyone who's outstayed their welcome — they leave for good

Roles — Doctor, Farmer, Scout, Guard, Chef, Hunter, Scavenger — that shift your odds on runs and events

🎒 Survival Systems

Go Scavenging — send a Sim to pick over abandoned locations (rabbithole grocery, pharmacy, police station, hospital, quiet suburb) with real risk/reward. Age, traits, and roles all matter.

Check Supplies — see everything your household is carrying

Buy a Survival Knife — +20% fight odds and the ability to put zombies down for good, with a fully custom knife-stab animation

🧵 Rebuild What You Wear (needs a sewing machine) COMING SOON

The stores are gone. Your clothes fray and tear every ~2 sim-weeks, saddling your household with an uncomfortable Ragged Clothes moodlet. Sit at a sewing machine, spend leather, and jump straight into CAS to stitch a fresh outfit.

💿 Optional DLC-Enhanced Features

Outbreak is 100% playable on base game, but if you own these packs, extra systems switch on automatically:

🐄 Cottage Living — Go Hunting: send a Sim out to bring back raw meat and leather, which feeds the whole sewing/clothing loop above.

🎨 Custom Content

Included in the mod: all custom zombie animations (idle, lunge, recoil, death, corpse, knife stab), the possessed shamble walkstyle, a custom "Outbreak" pie menu with its own biohazard icon, and the red hover titles.

Optional companion CC (separate downloads): the zombie skin, the survival knife mesh, and a survival sewing machine.
