Notice Regarding the End of Support for Windows 10

We sincerely thank you for your continual support of our company's products.
The following is a notice regarding the system requirements for our PC game software (Windows version).

On October 14th, 2025 (JST), Microsoft will be ending support for the Windows 10 operating system.
Accordingly, our company will also be ending support for Windows 10 on Tuesday, October 14th, 2025.

Should you continue to use Windows 10, you will still be able to play our games for some time after support has ended.
However, there may be cases where games will not run properly due to the application of future updates or automatic updates.
(Automatic updates refers to online games, etc., in which the program is automatically updated when the server is accessed.)

We would like to ask all affected customers to please take note of the support termination date and consider OS migration as soon as possible.

For information regarding the end of support for Windows 10, please refer to Microsoft's website.

If any other guidance becomes necessary, we will provide such guidance as soon as possible.
Thank you once again for your continued support and understanding.

Om detta spel

To commemorate Kou Shibusawa's 35th anniversary, the "Kou Shibusawa Archives" will be opened in the Steam Store. Here we will revive popular previously released titles.

In this eleventh round of releases, we offer "Romance of the Three Kingdoms 12 with Power Up Kit," an expanded version of the 12th game in the series.

The stage is set. Create the story.

Throughout the course of Chinese history, upset victories, like the Battle of Guandu and the Battle of Chibi, have proliferated. To make this kind of dramatic battle possible, we have included special large scale strategies called Gambits. Also in these climactic real-time battles, the key to victory is using strategies that best mesh with the rapidly changing conditions on the battlefield. Through the Power Up Kit, the Gambit system has been improved, City Technologies, Foreign tribes, new equipment, and an officer/strategy editor have been added.

Note: Neither "Online Battle" mode nor DLC are supported for this product.
