All units are controlled by the AI unless the player directly intervenes, and battles between forces are carried out in real-time.

While in control of a unit, players are able to use special skills or magic spells to turn the tables, although enemy characters are also able to do so.

A significant change to the story involves a romance between Liu Bei and the character Diao Chan, being a significant factor behind Liu Bei's decision to go to war, and Himiko, a semi-fictional sorceress (the historical Himiko ruled Wa [ancient Japan]).

In addition to the fantasized theme, Kessen II departs from its realistic predecessor.

Koei introduces elements of magic, especially with the portrayal of notable strategists such as Zhuge Liang and Sima Yi as sorcerers.
