Server-Admin Simulator

Build. Manage. Dominate.
You didn't just rent some rack space. You built an empire.
Start with a single server in a rented closet and grow your operation into a full-scale datacenter powerhouse. In Server-Admin Simulator, every decision matters — from the hardware you install to the contracts you accept, the staff you hire, and the rivals you crush.
This is not just a tycoon game. It's a power trip.

Your Datacenter. Your Rules.
Every rack you bolt in. Every CPU you upgrade. Every contract you sign. It all adds up — or it doesn't, and you go bankrupt.
Build your infrastructure from the ground up:
Purchase server racks with different cooling and power profiles

Install and upgrade CPUs, RAM and network cards across multiple tiers

Accept client contracts — from small websites to massive AI training clusters

Balance income, energy costs, staff salaries and loan repayments

Expand your datacenter room by room as your reputation grows

The market doesn't wait. Rivals will steal your clients. Random events will knock your servers offline at the worst possible moment. Your job is to stay online — no matter what.

Hire Smart. Manage Smarter.
You can't do it alone. Build your team:
Cooling Engineers — keep your hardware from melting

Security Experts — reduce the risk of random incidents

Network Engineers — slash repair times

System Administrators — automatically accept contracts while you sleep

Every employee levels up over time, becoming more effective the longer they work for you. But they also demand raises — and they will leave if you don't pay up.

The Dark Side of the Datacenter
Not all revenue streams are... official.
Unlock the underground side of the server business: run hacking operations against rival infrastructure, browse the Zero-Day market for exploits, and take on Government contracts that come with strings attached — and serious consequences if you fail.
Simon-Says hacking minigame with scaling difficulty

Zero-Day exploit market — buy, deploy, profit

SLA penalties for downtime on high-stakes contracts

Investigation system: push too hard and face the consequences

Walk the line between legitimate datacenter operator and digital criminal — or commit fully to one path. The story branches based on your choices.
A Story That Reacts to You
Server-Admin Simulator features a full branching campaign with two distinct endings:
↗ The Legal Path — build your reputation through legitimate contracts, acquire rivals and become the most trusted datacenter in the region.
↙ The Underground Path — embrace the shadows, dominate the black market and become the most feared operator in the network.
13 missions. Real consequences. No going back once you choose.
