About

Crack the code before your rival does. Protocol 4 is a hacker game of pure deduction. Every guess gives you signal readings; you break the passcode with logic, not luck. Play solo, take on the Daily Operation, or duel another operator in real time. REAL-TIME PvP DUELS Race: one passcode, two operators. First one through wins. Standoff: each of you sets the code the other must break. Two codes, one clock, and you watch them close in on yours. Outsmart your rival and claim the reward. DAILY OPERATION A new code every day, the same for everyone. Crack it, climb the daily leaderboard and earn double XP. 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 one of three syndicates, 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. MORE WAYS TO PLAY Quick Hacks for fast action, Training to sharpen your deduction, and 18 career contracts plus fresh daily missions. ARSENAL OF TOOLS Oracle Scan, Double XP and more hacking tools to gain the upper hand when a code will not give. Play in English, Turkish, Spanish, French, German or Portuguese, on iPhone and iPad. Are you ready to initiate Protocol 4?
