Defend the network

Play Blue against the computer. Rounds are untimed and resolve as soon as you lock in, with the tutorial on your first match.

Attacker difficulty

A scripted attacker that probes what is exposed and works toward the records step by step.

Play a friend

Two-player mode: one of you attacks as Red, the other defends as Blue, and you swap sides for the rematch.

Create a private room

Your side

Join with an invite link

Opening an invite link directly works too. Rooms are private: only someone with the link can take the second seat.

Practice as Red

Try the attacker's side against a scripted defender.

Defender difficulty

Triages alerts, hunts and purges intruders, and weighs requests, but takes ones it cannot place at their word.

Plan in secretBoth sides queue moves at the same time. Each move shows its cost, timing and what the other side might notice before you commit.
Read the evidenceBlue sees alerts and log lines, some of them harmless business noise. Red sees only what it has discovered.
Swap and replayAfter the reveal, rematch on the same board with sides swapped to settle the duel.
