THE PROTOCOL // CYCLE 7 // SIMULATION ONLINE
A roguelite card battler for iPhone. Pick a machine, fight through eight lethal sectors, take the core of every machine you beat, and reach the Nexus.
Can't wait? Test the free iPhone beta now.
// How a run works
Eight sectors, then the Nexus. Lose once and the run is over, so every card, every core and every choice of path counts.





// The starters
Six machines walk out of your first packet. Each has its own kit, a home sector that helps it, and a weak spot the Arena will find.
CORE BUDGET 420ALLOCATED 420
// The archive
Eight clans, twelve machines each. Meet one in a run and its dossier is declassified. Beat it and it's stamped DEFEATED. Earn Protocol Data to unlock it and play. Never random. Always earned.
