๐ง OUTBREAK โ 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!
๐ A World That Falls Apart in Phases
Trigger the collapse yourself and watch society unravel across five escalating stages:
Dormant โ life as normalโฆ for now
Rumors โ something's wrong. A lone shape in the dark.
Outbreak โ the dead walk. People start to turn.
Collapse โ the streets belong to them. Careers end. School's out forever.
Endgame โ 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.
๐ง The Horde โ Built for Realism
Slow shamblers that never run โ realism is the whole point
Your actual neighbors rise as the dead โ 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 4โ6 sim-days before drifting on โ a real infestation, not a spawn blip
Up to 8โ12 zombies around your lot at peak
Dull perception โ they sense you ~12m outโฆ 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 โ no phones, no snacks, no chatting
No special NPCs get infected (Grim, Father Winter, mascots, etc)
A bite starts the clock: Bitten โ Fever โ Delirium โ turned. Check a Sim's infection status, and when one of your household finally succumbs, they're lost to the horde โ gone, shambling away wearing a face you used to love.
โ๏ธ Combat โ Dangerous but Fair
Encounter chance cards when the dead get close: fight or flee
Weapon-aware odds โ your fitness and your best weapon tilt the fight
Fight Off any zombie directly โ your Sim walks up and struggles
Injuries from bad rolls: sprains, deep cuts, and rare permanent wounds
โฐ๏ธ Corpses โ Put Them Down for Good
An armed kill drops a zombie permanently โ 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 โ the only way to truly dispose of them. Watch them burn away.
๐ง Survivors โ Rare and Precious
Wandering survivors occasionally appear (rarely โ 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 โ they leave for good
Roles โ Doctor, Farmer, Scout, Guard, Chef, Hunter, Scavenger โ that shift your odds on runs and events
Go Scavenging โ 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 โ see everything your household is carrying
Buy a Survival Knife โ +20% fight odds and the ability to put zombies down for good, with a fully custom knife-stab animation
๐งต 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.
๐ฟ Optional DLC-Enhanced Features
Outbreak is 100% playable on base game, but if you own these packs, extra systems switch on automatically:
๐ Cottage Living โ Go Hunting: send a Sim out to bring back raw meat and leather, which feeds the whole sewing/clothing loop above.
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.
Base-game safe, works alongside your other mods
Uses safe injection โ no core file overrides
