Sea Land Air: Four Nations War

About the Game

Four sides. Two alliances. One hidden battlefield.

Sea Land Air: Four Nations War is a four-player 2v2 strategy game built around concealed armies. Each player secretly deploys 33 pieces across a 38-cell base, joins forces with the opposite seat, and advances through a shared battlefield where every branch follows different routes.

Command land, sea and air

Army pieces fight along railways and roads, with engineers able to turn and travel long distances by rail. Naval units control sea routes and exchange fire with linked coastal batteries. Air units turn along air routes and cross the front. Reconnaissance airships can hover over pieces to reveal live information, but that intelligence disappears as soon as the stack separates.

Read the battlefield

Enemy identities remain hidden. Movement patterns, deployment rules, combat outcomes and reconnaissance gradually narrow the possibilities. Locate flags, avoid mines, spend bombs wisely and protect the officers your opponent is hunting.

Play alone or with others

Single-player includes standard and hard AI; hard enemy AI has complete piece information. Multiplayer supports Steam networking, LAN and a direct-connect fallback, while the host can fill empty seats with independent AI. Eight interface languages are supported locally, so players in the same room can use different languages.

A changing cast of nations

Every match assigns different World War I nations and period flags to the four seats.
