Sengoku: Road to Unification

What it is

Sengoku is a turn-based strategy game written here at Kalgoorlie Retro Gaming. Choose a clan in the 1560 or 1582 scenario. Each month your governors cultivate land, develop towns, reinforce castles, hire and train soldiers and sell rice; you propose alliances and send ninja to stir up your rivals' provinces. Spring brings in the trade gold and autumn the rice harvest, while summer typhoons and unhappy provinces can undo your work.

When you invade a neighbouring province you fight the battle yourself on a hex field: three units a side, with rifles, charges, cavalry and ambushes, forests and mountains, and a castle for the defender. Destroy the enemy commander to take the province. Hold all thirty-eight to win.

You can also play it in your web browser, with nothing to install. The browser edition is the same game, version 1.2.0, and it saves in your browser. Export and Import move a campaign between the two editions as a save file.

Multi-player games: choose Multi-Player game on the title screen of the browser edition. Make a player name, start a game and give your friends its invite code, or join theirs; up to eight players each lead a clan. Orders take effect at once, and you fight your own invasions on the hex field. The month ends when everyone has ended their turn, or at a time limit the game's creator chose (12 to 72 hours); anyone who has not played by then has their month played by the computer, and keeps their clan. You get emails about your games (you can turn these off). Multi-player games are played in the browser edition only. More in the documentation.

Features

Installing

Windows

1. Download Sengoku-1.2.0-x64.msi and run it. It installs for your user only, so no administrator password is needed, and adds Sengoku to the Start menu and the desktop.
2. The installer is not code-signed, so Windows SmartScreen may warn you first: choose More info, then Run anyway.

Linux

1. Download sengoku_1.2.0_amd64.deb and install it:

   sudo apt install ./sengoku_1.2.0_amd64.deb

2. Start it from the Games menu, or run sengoku.

Saves are kept in %LOCALAPPDATA%\Sengoku - Road to Unification\saves on Windows and ~/.config/Sengoku - Road to Unification/saves/ on Linux, and are left alone when you uninstall or upgrade. Saves from earlier versions load in this one.

Downloads

Version 1.2.0, 4 November 2026.

Also on the BBS in the file area Heisenbergs Files. The player guide and the release notes are here to read first; there is more in the documentation.

What's new

1.2.0: Export and Import. In Campaign > Save, Export to a file saves the campaign to a file you choose; in Load, Import from a file opens one. The file is the same in both editions, so a campaign can move between the browser and the desktop. The desktop edition now saves itself at the end of every month, and Continue on the title screen picks up from there, as in the browser.

1.1.0: the first desktop release. Multi-player games in the browser edition, for up to eight players. Saves are now format 3, which can hold several players' clans; older saves still open.

1.0.0: the browser edition, put up on 3 November 2026.
