Production Empire: Factory Sim

Build a factory. Automate everything. Grow a production empire that keeps running while you are offline.

Production Empire is an idle factory simulator and tycoon game about turning raw ore into starships. Mine iron, refine steel, stamp gears, assemble motors, build robots, then chain it all together into one self-running industrial machine.

⚙️ A REAL PRODUCTION CHAIN
• 229 resources across 11 tiers, from Wood and Iron Ore to Fusion Reactors and Dyson Sphere Components
• 168 crafting recipes with genuine multi-input bills of materials
• 60 buildings: mines, sawmills, smelters, oil refineries, chemical plants, semiconductor fabs, robotics plants, starship yards
• Nothing is a reskin. Every tier is built out of the tier below it.

🏭 BUILD AND AUTOMATE
• Place buildings freely on your factory grid
• Route output with rotatable conveyor belts
• Buffer with warehouses, cash out through markets
• Watch throughput, find the bottleneck, fix the bottleneck. The core loop of every great factory game.

💤 IDLE PROGRESS AND OFFLINE EARNINGS
• Your factory keeps producing while the app is closed
• Come back to full buffers and a bigger bank balance
• No timers gating your progress, no energy bar, no waiting to play

📋 CONTRACTS, GOALS AND PROGRESSION
• Fulfil contracts for steady income
• 3 rotating weekly contracts for bigger payouts
• 32 achievements, from First Dollar to Legendary Factory
• 7-day login streak with doubling rewards
• Product quality tiers that multiply your sell price
• Detailed production statistics and throughput history

🚀 FROM SAWMILL TO STAR FORGE
Tier 0 is a wood harvester and an iron mine. Tier 10 is a Matrioshka Brain, a Wormhole Generator, a Star Forge, a Universal Constructor. Between them: planks, ingots, gears, circuit boards, CPUs, electric motors, robotic arms, drones, electric vehicles, quantum computers, fusion reactors, space stations and megastructures.

✅ NO ADS. NO IN-APP PURCHASES. NO PAYWALL.
Genuinely none. No forced videos, no premium currency, no "skip the wait for $4.99". The entire tech tree is free, and progress is earned by building a better factory instead of by paying.

📱 BUILT TO RUN WELL
• GPU-accelerated rendering, smooth with hundreds of buildings on screen
• Plays fully offline. No account, no login, no internet needed.
• Autosave, so you never lose an empire

🎯 MADE FOR PLAYERS WHO LIKE
Factory games and factory builders, idle games and incremental games, tycoon and business simulators, production line and assembly line automation, logistics and conveyor puzzles, resource management and crafting, industrial empire and city building, clicker progression with real depth, offline idle tycoons, engineering and optimisation sandboxes.

If you have ever redesigned a whole factory floor because one belt was 12% under capacity, this game is for you.

🔧 WHY IT KEEPS YOU PLAYING
The fun is not a number going up. It is the layout. A mine feeds a smelter, the smelter feeds a stamping press, the press feeds an assembly plant, and somewhere in that chain one building is starving. Find it, rebuild that section, watch the whole factory speed up. Then unlock the next tier and solve a harder version of the same puzzle.

Start with one wood harvester. Finish with a star forge.
