• Taishi Ci changed from a spear back to his pair of rods.

Because the game was supposed to be a complete revamp for the series, no new characters were added in this installment. In fact, characters Pang De, Xing Cai, Jiang Wei, Da Qiao, Zhu Rong, Meng Huo, and Zuo Ci from the previous installment were omitted, and are only referenced in certain campaigns.
