Ma Su participates as a lesser-officer in many battles. At the battle of Yi Ling, Ma Su, along with Wang Ping, will appear as reinforcements under Zhuge Liang, after the Wu army has succeeded in their fire attack and Liu Bei has escaped through the stone sentinel maze and arrived safely in the main camp. However, his major role comes at Jie Ting, when he leads the Shu army against the Wei army lead by Sima Yi. Similar to what occurred historically, Ma Su sets up the main camp upon a hill, allowing the Shu forces to be surrounded. The goal for the Shu army in the battle is to hold off the Wei forces and protect Ma Su until Zhuge Liang arrives with the main unit. The goal for Wei is to defeat him before the unit can arrive. In some scenarios, he will also appear at the Battle of Wu Zhang Plains.
