Hack Ex 2 is a free-to-play, real-time multiplayer hacking game for iOS and Android, developed by CNC Apps, LLC. Players compete by scanning for targets, breaking through device defenses, accessing in-game wallets, and uploading viruses that can generate income or hinder opponents. No real-world hacking knowledge is required.

Rebuilt as a sequel, the game introduces a new app, accounts, and economy, along with updated balance and progression. Players can form or join crews of up to 20 members, communicate in encrypted channels, and use rootkits to weaken targets for their teammates. Daily missions and login streaks offer opportunities to earn crypto and experience points.

Gameplay combines offensive software, including firewall bypassers and password crackers, with defenses such as firewalls, encryption, antivirus tools, proxies, and wallet shields. Additional utilities and viruses provide ways to manage notes, generate software keys, siphon incoming crypto, or disrupt rival devices. A rotating Black Market offers single-use items, while optional Overclock credit bundles and crypto stashes are also available.
