Netbreak

Netbreak puts you at the controls of a simulated cyberpunk operating system. You work from a terminal, email client, network map, file browser, darkweb browser, skill tree and blue-team SOC dashboard. Its five-act campaign follows your work as an operator drawn into a conspiracy surrounding GHOST PROTOCOL, a mass-surveillance AI.

Breach and investigate

You use over 100 working commands, including nmap, hydra, ssh, scp, sqlmap, nikto, hashcat and wireshark. Chain reconnaissance, exploitation and data theft; write shell scripts with variables, loops and conditionals; and use tab completion, pipes and log-covering tools. You fingerprint hosts, find open ports, match services against a database of 18 real-world CVEs, break in and steal data.

You can brute-force logins with escalating wordlists, dump configuration files and follow clues operators leave behind. Every action raises your trace: wipe logs, route through proxies and disable the IDS to avoid detection, or risk the meter climbing until your targets come after you. Before probing a port, you can use OSINT to profile targets through social media, public records, breach dumps and job postings.

Work both sides

You can also defend networks through the SOC Dashboard. Tune intrusion detection, deploy honeypots, correlate SIEM events, isolate compromised hosts and conduct live forensics against AI-driven attackers.

The game also lets you target people rather than systems. Run phishing campaigns against 14 named targets, spoof caller IDs, voice-phish your way past reception, clone badges and tailgate into buildings.

Darkweb operations

The darkweb becomes accessible for the right price and reputation. You can deploy rootkits to maintain persistence, build a botnet from machines you own, run ransomware and craft single-use zero-days. Each dark operation has consequences with the factions watching you.

A reactive world

Five factions have reputations, territories and wider effects: helping one can make another your enemy. AI sysadmins respond to intrusions by changing passwords, patching the exploited vulnerability and raising alarms. Rival hackers have names and agendas, and may help you, sabotage you or get themselves arrested. Adaptive difficulty adjusts to how you are doing.

Skills and story

Earn skill points across three trees: Technical, Social Engineering and Defense, with 24 nodes in total. Spend credits at the Shadow Market on tool upgrades, hardware that changes how the game plays, wordlists and intel dossiers.

The five-act campaign contains over 100 missions. The legend ZERO draws you out of obscurity and into the GHOST PROTOCOL conspiracy, while your decisions about whom to betray, what to sell and whom to save lead to one of five distinct endings: burn it all down, sell out, go corporate, join the architects or vanish.

Learn the tools

A pressure-free warmup teaches you the tools one step at a time, with no trace, clock or jargon wall. The game retains its deeper systems for when you are ready to use them.
