September 10, 2026 | To mark the start of Steam Programming Fest, Static Signal is excited to announce that Persistence, Blackdoor’s biggest free update yet, is now live for all owners of Blackdoor, available on Steam for $12.99 / £11.75 / €13.49. For fans of Hacknet or Grey Hack, this is the real thing, a terminal, real scripting, no shortcuts.
Even Blackdoor’s own website plays by the same rules, visit blackdoor.tools to boot up a real, interactive terminal and type your way through the site itself. A free demo is also available on Steam.
The Persistence Update: Servers That Fight Back
Every server you break into in Blackdoor is alive now. Get sloppy while you’re still connected and the system doesn’t wait until you log off to notice anymore, it reacts in real time: rotating the account you just cracked, killing the port you got in through. Plant a script before you disconnect and it keeps working without you, ready to react the next time you’re back in-game and something it’s watching for actually happens. The people running these systems remember you too, push them too hard and they get harder to crack, or hand you off to someone worse. This is the update where hacking stops being a puzzle that holds still and starts pushing back.
“I love playing hacking games, and creating Blackdoor was my chance to contribute to that space and try my best to push it further. Scripting was my first idea for doing that. Persistence is the second, servers keep doing things in the background while you’re writing scripts or hacking somewhere else, and your scripts can keep working across multiple systems at once. It makes Blackdoor feel less like a collection of static hacking puzzles and more like something that actually reacts to you and your actions,” said Static Signal, the solo developer behind Blackdoor.
About the Game
You’re a hacker with a terminal, four terrible scripts, and an anonymous contact who needs files from places they really shouldn’t be. The scripts were free, and you can tell.
Your port scanner checks all 65,535 ports, which is thorough and also going to take longer than you have patience for. Your password cracker just brute-forces everything and wakes up the intrusion detection system doing it. Both will technically get the job done, the way a spoon will technically dig a tunnel.
So you rewrite them, and the new probe only checks common ports and finishes in seconds, while the new cracker skips guessing entirely and reads the admin’s own password hints straight off the filesystem. Nobody told you to fix these – you just got tired of using tools this bad. That’s Blackdoor – you write the code, the code hacks the servers, and better code hacks them faster, quieter, and before the trace catches up.
Not a hacking-themed clicker. An actual terminal.
There are no buttons, no “press X to hack”, no minigames where you rotate pipes or match symbols. You sit at a command line with tab completion, a built-in code editor, and the full set of commands you’d expect – and you write scripts in a custom Python-like language that was built to be fun to learn and satisfying to master.
If you’ve never programmed before, it’s more sink-or-swim than a tutorial – you’re straight into scripts that already work but could work better, picking up variables, loops, and functions by actually touching them. If you have, you’ll skip past the basics quickly and start writing proper tooling. The language is close enough to Python that your instincts will carry over. Either way, the regulars will accidentally teach you things by arguing about it in IRC.
The Job
Your contact goes by second_hand, who operates through #blackdoor – a small IRC channel populated by hackers, script kiddies, and at least one person who thinks printing “hello” counts as a proof of concept – and doesn’t do small talk. You get a server IP, a brief explanation of what’s on it, “good luck”, and payment on delivery.
You’re not alone in here
You’re never alone in #blackdoor. Hackers chat while you work – sharing tips, posting side jobs, placing bets on whether anon42 can find a port (he can’t). Your contact DMs you mission briefings, and the channel reacts when jobs get done. Like any real IRC channel, most of the advice is unsolicited and some of it is wrong.
#lounge is a live channel where real players talk about anything – help, questions, scripts, general chat. It’s not moderated in real time, though Steam’s text filter still applies.
Your code, your rules
There’s no right answer – you get targets and tools, and how you combine them is entirely up to you.
Key Features
- Write real code: A custom scripting language designed for hacking, not buttons or minigames. Your code runs line by line, and you see exactly why it’s slow.
- Hack servers: Probe ports, crack passwords, explore filesystems, escalate privileges, steal data. Every server has its own users, files, and weak points to find.
- Race the trace: Every connection starts a countdown that speeds up the more noise you make, and getting traced ends it right there.
- A real terminal: Tab completion, command history, a code editor – no theming, no skin over a menu, this is the actual interface.
- Upgrade your rig: Faster hardware means faster scripts, better tools unlock new capabilities, or just save your money and write better code instead.
- Story campaign: An anonymous contact, escalating jobs, a corporate conspiracy, and a secret that might be worth more than the pay.
- IRC: Hackers chat, argue, and accidentally teach you things while you work, and side jobs and tips both get shared along the way.
- Your approach: No fixed solution – write surgical tools or blunt instruments, find passwords in config files or brute-force them, and if you find a shortcut nobody else did, that’s the point.
- Live community chat: #lounge connects you to other players. Ask questions, share scripts, compare notes.
- Workshop: Share scripts and entire campaigns, download community tools, and see how other people solved the same problems.
