About

Step into the world of elite hackers with Protocol 4! Your mission is to crack secret codes using pure logic, deduction, and specialized hacking tools. Play the high-stakes Daily Challenge, climb the Global Leaderboards, or challenge another operator to a real-time PvP Duel! Features: REAL-TIME PvP DUELS: Race another operator to the same code, or play a STANDOFF where each of you sets the code the other must break. Stake your credits — the winner takes the pot. BUILD YOUR EMPIRE: Assemble mining rigs, expand your vault, and run overclocks. Your network keeps earning credits while you are away. SYNDICATES AND TERRITORY: Join a syndicate, claim territory on the map, and take your share of the pot that every raid feeds. RAIDS: Break into a rival operator's grid and take what they left unguarded — then set your own defenses before they come for you. GLOBAL LEADERBOARD: Earn XP and climb fifteen ranks to become the ultimate Server King. MULTIPLE GAME MODES: Play Quick Hacks for fast action, Training to hone your skills, or the Daily Challenge for massive rewards. ARSENAL OF TOOLS: Use advanced tools like Logic Analyzers, Time Warps, and Oracle Hints to gain the upper hand.

What's New in Protocol 4

3.0

September 5, 2026

NEW DUEL MODE: STANDOFF The live duel used to be a race — one code, both of you deducing it. Now you can play a standoff instead: each of you sets the code the other has to break, so there are two secrets, and you watch their readings land on yours while you work on theirs. Turns alternate, and a solve only ends the match once both sides have had the same number of turns — so going first is never the thing that wins it. Solve on the same turn and it is level, a result no duel could produce before. BUILD YOUR EMPIRE Assemble rigs, expand the vault, run overclocks. Your network keeps mining while you sleep. SYNDICATES AND RAIDS Join a syndicate, claim territory, raid rival operators. A share of every raid now feeds the syndicate pot instead of conjuring credits out of nothing. CAREER 18 contracts, daily missions, and a rebuilt rank ladder where competitive play finally counts. ALSO IN 3.0 • Reinstalling no longer wipes your progress: credits, rank, badges and empire all come back • Finishing a duel and wanting another takes you straight back to the open-duel board • Rejoining a duel gives you back the code you were defending • A drawn duel now shows both solves instead of crediting only one • Defence tools are charged properly instead of quietly paying for themselves • A real iPad layout instead of a stretched phone • Six languages across every screen • Block, report, and codename filtering • Reduce Motion and Dynamic Type honoured throughout • Push notifications for raid alerts and duel invitations
