How to Get Zhang Fei and Guan Yu 5 Special Moves:
During the first battle, the Battle of Xu (on expert level), have Guan Yu defeat Li 
Dian and then go attack their storehouse, which is located just past the upcoming 
bridge. You get lots of experiance when you destroy their supplies. After you do 
that, have Liu Bei lose on purpose to Xiahou Yuan. Repeat this alternating Guan Yu 
and Zhang Fei back and forth, until you get too strong so you cannot lose, even if 
you try. (Note: When it is Zhang Fei's turn he defeats Yue Jin.) 

Dynasty Warriors 4 reference:
During the FMV sequence where the two men are talking amongst themselves 
about Cao Cao and Liu Bei, zhao yun is sitting there listening. Look behind him to 
catch a glimpse of the character Gan Ning from Dynasty Warriors 4 going to sit 
down. What makes this unique is that the Gan Ning in the game is totally different 
looking.
