Dynasty Warriors
In Dynasty Warriors 5, players can select either Sun Quan's forces or Huang Zu's forces. With Sun Quan, your main objective is to stop Huang Zu's fleet and then defeat him. This can be achieved by going straight for Cai Mao and Gan Ning. Then traverse north to Huang Zu. Taking out all Huang Zu's officers outside the fortress should lower his morale, doing so will make him more vulnerable. If players select either Sun Ce or Da Qiao for this stage, then the former will take Sun Quan's place as commander of the Wu Army.

With Huang Zu's forces, players are to tasked protected the fleet and defeat all the generals and sub-generals. Zhou Yu isn't part of them so you won't need to go for him. But leaving Zhou Yu could mean that he meets with Cai Mao's fleet and defends when they land at the camp. After they land, Sun Quan will be no trouble.
