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 fourth round of releases, we offer "Romance of the Three Kingdoms Ⅳ with Power Up Kit," which was released in 1994 as an expansion to the 4th game in the series. About 450 officers appear in the game and "Frontier Tribes" have been added as a diplomatic element. In battle, in addition to the standard field and castle battles, we also include final battles inside the castles and large weapons like chariots and catapults.
