|Completing this stage will start you on the Hypothetical route for Shu. In orderto unlock the option, you must get all of the stars on the stages prior to this one on the stage select screen. Once you do, talk to Xu Shu in the camp to start the battle.|
Xu Shu's first task for you at the beginning of the battle is to capture the northern garrison, which is easily done by defeating the officer up there. This will cause some siege ramps to appear, so follow them to where they will be set up. Climb one of them and make your way to the floodgates, where you need to defeat Pang De to make sure the enemy doesn't use a flood attack.
The enemy troops in the middle of the map will start advancing and go after Guan Yu. Go and help him with the officers that come after him, which will cause Wu forces to appear in the southeast corner. Head that way, noting that some of the Wu officers will try to run past you, so make sure you defeat them before they get away.
The other Wu officers, which include Lu Su and Lu Xun will remain in thesoutheast corner, so head there and clear the area. At this time, Xiahou Dun will appear in the southwest and start heading for the floodgates. Move as fast as possible to the northwest corner to cut him off, noting that there will be other officers with him. It's a straight shot to Cao Ren after this, whose defeat will end the battle.
