Indie developer Li Zunlu, operating under LiTsunluROAD, is preparing to release Sea Land Air: Four Nations War, a turn-based military board game inspired by Chinese army chess that puts deduction, positioning, and hidden information at the center of its strategy. Unlike traditional strategy games where players can see every opposing unit, Sea Land Air: Four Nations War challenges players to interpret concealed deployments and determine when to commit their forces. The game combines land, naval, and aerial units with railway routes and a flag-capture objective, creating a battlefield where understanding an opponent's intentions can be as important as controlling territory. A free single-player demo is available on Steam, while the full game is currently targeting November 2026. The full release is planned to support multiple configurations, including four-player 2v2 battles and a six-player 3v3 mode that introduces hidden allegiances and private identity guesses. ## Hidden Units Turn Every Move Into a Clue ![](https://storage.ghost.io/c/eb/c3/ebc34dba-226d-448a-8bd7-25a7ee135adf/content/images/2026/10/image-48.png) The central idea behind Sea Land Air: Four Nations War is that players do not begin with complete knowledge of the opposing forces. Units are deployed secretly, leaving opponents to work out what they are facing through movement, reconnaissance, and combat. A piece advancing along a railway might reveal an opportunity to attack, or it could be bait intended to draw defenders away from a more important position. The ultimate objective is to capture the opposing flag, but reaching it requires more than simply advancing across the board. Players must protect their own positions while identifying which enemy movements represent genuine threats. In combined-arms modes, land, sea, and air units follow different movement routes and combat rules. Naval threats, railway access, and reconnaissance all add information for players to interpret. The result is a strategy game built around a recurring question: How much can you safely conclude from what your opponent has shown you? ## Six-Player Mode Adds Hidden Allegiances Perhaps the most unusual feature is Six Nations, the full game's six-player 3v3 mode. Rather than making every alliance immediately obvious, players draw identity cards that determine their roles and allegiances. Certain identities, identified as Q identities, are public from the beginning. Other roles remain concealed according to the mode's reveal rules. Players can make private guesses about other participants' identities, using battlefield behavior to inform their suspicions. Those guesses are personal notes rather than automatic confirmation of an alliance. The mode also introduces captured forces, cavalry, and flamethrower units, adding further tactical decisions to the larger battlefield. It's an interesting combination of team-based strategy and social deduction. Players must interpret not only where an opponent moves but also what those moves might reveal about their loyalties. ## Four Modes Offer Different Ways to Play ## Four Modes Offer Different Ways to Play From classic two-player strategy to six-player battles with hidden identities, each mode offers a different tactical challenge. Combined-Arms Strategy ### Sea Land Air 4 Players · 2v2 Combined land, naval and air forces, railway movement and coastal attacks. Traditional Board Tactics ### Classic Four Nations 4 Players · 2v2 Traditional hidden-rank strategy involving camps, mines and railway routes. Head-to-Head Combat ### Land Duel 2 Players A smaller-scale contest focused on deployment, deduction and capturing the flag. Hidden-Identity Warfare ### Six Nations 6 Players · 3v3 Hidden allegiances, drawn identities, private guesses and captured forces. **Note:** The six-player hidden-identity mode is a full-game feature and is not included in the free single-player demo. Beyond the main modes, the Steam listing describes tutorials, normal and hard AI opponents, saved formations, match recordings, and support for Steam, LAN, and direct connections. These features suggest that the developer is aiming to support both competitive multiplayer sessions and players who prefer learning the rules at their own pace. ## Free Steam Demo Available Ahead of Release Players can currently try a free single-player demo on Steam. The demo offers an opportunity to explore the game's mechanics before purchasing the full version, although the developer has clarified that the six-player hidden-identity mode is a full-game feature. The full release is planned for Windows PC. Its Steam listing currently gives a Q4 2026 release window, while developer Li Zunlu says the team is targeting November 2026. That distinction is worth noting: November is the developer's stated target, not a confirmed launch date on the storefront. The Steam page also lists English, Japanese, Simplified Chinese, Traditional Chinese, Korean, and several European-language interfaces. For players who enjoy turn-based tactics, board games, and hidden-information strategy, Sea Land Air: Four Nations War offers a less conventional approach to military competition. Its appeal lies not in how quickly players can react, but in how carefully they can read the board and one another. The game is available to [wishlist on Steam](https://store.steampowered.com/app/4886320/?ref=morganyte.com), where players can also download the demo and view gameplay footage.
