Sea Land Air: Four Nations War

Every move gives something away

A piece advances along the railway. A ship threatens your coast. Is that an opening, or bait? Deploy in secret, probe hidden units and decide when you know enough to attack. Protect your flag while looking for a route to theirs.

Six players. Two sides. Who can you trust?

Six Nations brings the war to a six-sided board in 3v3. Draw identity cards to determine your role and allegiance. Q identities are public from the start; other roles remain concealed under the mode's reveal rules. Watch who attacks whom, save private identity guesses and revise your reads as the board changes. Captured forces and the cavalry and flamethrower units add new decisions. Your guesses are personal notes, not proof of an alliance.

Four ways to fight

Sea Land Air: four-player 2v2 with army, navy and air-force units, railway routes and coastal attacks.
Classic Four Nations: four-player 2v2 built around hidden ranks, camps, mines and railway movement.
Land Duel: a two-player contest of deployment, deduction and flag capture.
Six Nations: six-player 3v3 with drawn identities, hidden allegiances and captured forces.

Control the routes. Conceal your intentions.

In the combined-arms modes, land, sea and air follow different routes and combat rules. Reconnaissance can turn a guess into useful information. A threatened flag can draw defenders away from the real attack. Mark suspected pieces privately, test your opponent's reactions and commit when the risk is worth it.
