Important: Satisfactory saves are tied to a specific save slot name and session, not an account ID, so there's no ID-matching step — but you should still back up your existing save before overwriting it, and disable cloud sync (Steam Cloud / Epic Cloud Saves) first to avoid it re-syncing your old save over the new one.
C:\Users\[YourUsername]\AppData\Local\FactoryGame\Saved\SaveGames\common\ (paste into Windows Explorer, or press Win + R and type %localappdata%\FactoryGame\Saved\SaveGames\common).sav/.savs files by copying the whole folder to your desktop first..sav file(s) into the common folder.Save file naming: Satisfactory identifies saves by the name embedded in the .sav file itself (shown in the in-game Load Game menu) rather than a Steam ID prefix, so you don't need to rename anything to match your account — just drop the file into the SaveGames\common folder and it will show up as a new save slot. The save contains full world state: unlocked milestones and alt recipes, MAM research tree, factory building placement and connections, power grid, vehicle paths, and all collected Hard Drives/Mercer Spheres/Somersloops.
Satisfactory is a first-person open-world factory-building game developed by Coffee Stain Studios, released into 1.0 full release in 2025 after several years in Early Access. Players crash-land on an alien planet as a FICSIT Pioneer and are tasked with building increasingly complex automated factories — starting from simple iron and copper smelting, escalating through hundreds of intermediate parts, and culminating in launching a Space Elevator to ship components back to headquarters. The game can be played solo or in co-op with up to 4 players sharing a persistent save.
Progression runs through a Milestone and Tier system: unlocking new buildings, conveyor belt tiers, and vehicles by spending resources at each Tier's HUB terminal, while Space Elevator Phases mark the game's major overarching goals. Alongside the linear Milestone track sits the MAM (Molecular Analysis Machine) research system, which unlocks alternate recipes by scanning Hard Drives scattered across the map — these alt recipes are essential for building efficient, low-footprint late-game factories.
The game's signature appeal is its open-ended factory optimization: there's no single 'correct' way to route belts, balance production ratios, or lay out a base, and reaching 100% completion means having explored the entire map, researched every alt recipe, built infrastructure for Nuclear and Geothermal power, and completed the full Space Elevator sequence through Tier 9 — a project that easily takes 150-300+ hours for a completionist playthrough.
