As the battle begins, your first goal will be revealed to capture the bases at the foot of Mt. Bailang. There are a total of 6 of them and each one is guarded by a gatekeeper, which will open the gate for each one. Once they are open, defeating the officer inside will capture the base.
Once you get all six, you'll be tasked with going up the eastern side of the map and attacking the northern enemy base from behind. Chen Lin will likely begin his trek towards Cao Cao's main camp, but you should be passing him up along the same path, so take him out. Also, wolves will appear inside of the caves, but they shouldn't be any real trouble, so either kill or ignore them.
Go through the base up top, defeating the officer to open the gate that will lead to the targeted base. Jump down into it and then defeat Yuan Tan, which will open all of the central base gates. Go down the middle path and defeat Yuan Xi, who is the second Yuan. When you reach the second east-west corridors, you'll find that they are secret passages to the bases with the remaining Yuan.
It should be at about this time that some reinforcements will show up, but you should only have one Yuan remaining. Take the secret passage and take out the gatekeeper to open the gate, allowing you access to the base. There should only be the Yuan there, so he should be easy to take out. The battle is over once all three Yuans are gone.
|In order to get both stars on this stage, you need to make sure that Guo Jia survives. Despite the descriptions saying he needs to withdraw, he will likely stay on the battlefield, even if you fulfill the conditions. Follow the stage like normal, capturing the bases at the beginning. Once he starts talking about defeating the Yuan brother, ignore his mission and follow him as he goes along the eastern path through the caves. Guard him from any attacks and ambushes, including the Wuchuan reinforcements later in the battle.|
