HACKFEST

Build the rig. Image the OS. Break into CorpoMax. A hacking sim where the operating system is the game.

Coming to Steam

You start with an empty desk and a budget.

Order parts from Crapazon. Assemble the tower — every watt has to come from somewhere, every gigabyte counts, and without a NIC you’re not getting online at all. Power it on, image an operating system, boot into HackfestOS.

Then go to work on CorpoMax.

What you actually do

Crack firewalls

Get a foothold on the network — and find out fast whether the rig you built can actually take the door off.

Read the logs

Real employee names are in there, and tracing them is how you find the next way in. The puzzle is reading, not guessing.

Solve your way deeper

Every layer of the network is a lock with a real answer. No dice rolls, no stat checks.

Seed malware that prints money while you sleep

Rent out what you’ve compromised. The income keeps arriving whether you’re at the desk or not.

Inside the machine

You were fired. Time for payback.

The loop

Better rig → faster hacks → more money → better rig. Hardware is the progression system, and it’s all diegetic: no XP bar, just a machine you built getting genuinely more capable because you bought the right part.

The whole thing is the OS.

There are no menus laid over the top. You are operating a computer that doesn’t exist. Windows, a file browser, a terminal, a store, a phone — everything you do, you do inside a machine you assembled yourself.

Get it

Start with the free browser demo — no download, no account, no launcher. The full game is $5, and there’s a Windows build if you’d rather own it. A Steam release is coming.
