Yeah and look something interesting things from the game:
-Shanks first use normal gun explosion attacks, then he use advanced CoA and you can see the red beams, you can see he combinate his advanced CoA to use the gun with open up the possibly how BenBeckman and Yasopp fight too.
-Shanks cover his sword with a large red aura, not only the AP becaming greater, but also his sword(or at least the red aura) became larger which give him better range fight skills
-Shanks can throw red lighting around his area
-Shanks can make a storm with the power of red lightning(advanced CoA)
-Similar like Yami(Black Clover) it seems like Shanks can use dimension slash attacks who cover the whole area
-In the previous PW3 Shanks also make the time slower for his enemy, he was with it far faster
It seems like the game hint his power and what it gonna look like someone use advanced CoA.
I think we see now how Gunmans like BenBeckmann and Yasopp fight, also we see how advanced CoA look like when a swordman cover his sword. Roger vs Whitebeard already show similar things and the game probably show the future skills of advanced CoA in the manga.
The only thing which the game not show much is the form of advanced CoC, im sure BenBeckman/Shanks/Roger had it and it give a other insane powerup which we probably see in the future when Oda reveal the true power of Kingshaki.
