Server-Admin Simulator

Server-Admin Simulator is a datacenter management game with a branching campaign. You start with one server in a rented closet and build toward a full-scale datacenter, making decisions about hardware, contracts, staff and rival operators. You balance revenue against energy costs, salaries and loan repayments while trying to keep your servers online and avoid bankruptcy.

Build your datacenter

You purchase server racks with different cooling and power profiles, then install and upgrade CPUs, RAM and network cards across multiple tiers. Contracts range from small websites to large AI training clusters. As your reputation grows, you can expand the datacenter room by room.

Rivals may take your clients, and random events can take your servers offline. High-stakes contracts carry SLA penalties for downtime, so your infrastructure and finances must withstand disruptions.

Hire and manage staff

You can hire four types of employees, each with a different role:

• Cooling Engineers: keep hardware from overheating.
• Security Experts: reduce the risk of random incidents.
• Network Engineers: reduce repair times.
• System Administrators: automatically accept contracts while you are away.

Employees become more effective as they level up, but they also ask for raises and may leave if you do not pay them.

Choose your path

The campaign has 13 missions and branches according to your choices, leading to two distinct endings. On the legal path, you build a reputation through legitimate contracts, acquire rivals and aim to become the region’s most trusted datacenter. On the underground path, you pursue the black market and seek to become the network’s most feared operator.

The underground side of the business includes hacking operations against rival infrastructure, a Zero-Day market for buying and deploying exploits, and government contracts with serious consequences for failure. Hacking uses a Simon-Says minigame with scaling difficulty. An investigation system tracks how far you push your illegal operations.

Game modes

Four difficulty modes change the challenge: Beginner has a relaxed pace and lower penalties; Normal is the intended experience; Hard brings more aggressive rivals and tighter margins; and Ironman uses a permadeath economy with no second chances. Endless Mode removes the campaign’s ending, while New Game+ lets you restart with prestige bonuses carried forward.

Multiplayer

Steam multiplayer supports up to four players in invite-only sessions, with no dedicated server or manual IP entry required. Competitive matches give each player an independent datacenter; players race to reach an earnings target and can follow progress on a live scoreboard. In Cooperative mode, everyone manages one shared datacenter together.

You can host from any save slot or start a new game. Friends can join through the Steam overlay or join an in-progress session from their friends list. Lobbies include ready checks and a force-start option, and competitive matches keep a history of results. All players must use the same mods.

Mods and other features

The official ModSDK provides a C# interface with IntelliSense documentation. Mods can add hardware, contracts, staff, software, rivals, terminal commands, news headlines, seasonal events and Zero-Day exploits. Fourteen lifecycle hooks let mods respond to game events; the SDK also supports localization and multiplayer-safe synchronization. An in-game Workshop browser lets you find and subscribe to community mods.

The game also includes Photo Mode with multiple frame styles, achievements, daily and weekly challenges, and global and friends Steam leaderboards.
