Actually the best in the series !
Have played all Shin Sangoku Musou and this one is definitely the ultimate one in the saga.
You can choose your own music from all Shin Sangoku Musou game ! You can choose your allied and the ennemy you face. You can play with a lot of generic officer (and they are really fun). Can creat until 10 edit officer like in Shin Sangoku Mushou 4 Mushouden
You can listen to the voices of all characters (and they are awesome in japanese). The voice are soo credible that you feel like you where in the middle of the battlefield. There a 200 pictures to unlocked. During a battle you can give order to your allies, you also can do that they follow you wherever you go (kind of compagnion or bodyguard) like in mode Xtreme of Shin Sangoku Mushou 4 Mushouden. If you are the kind of person who whants to finish the game at 100% you will have a LOT to do. Shin Sangoku Musou 4 Empires is extremely fun to play with a friend. So if you are looking for a good 2 player game (co-op), no need to search anyfurther.
