A Few New Things from the New Kingdom Hearts III Trailer (6/2017):
All Party Members Fight + Herc is FINALLY a party member!!!! (I know he was in BbS, but it was only for a bit).
LOOK AT DAT FIRE HAIR!!!
“Counter Shield” is the name for the new Keyblade’s Form Change. Seems to activate via Style Change.
The Kingdom Key doesn’t seem to change (as far as I know), but does grant “Second Form,” which lets Sora use moves like Sonic Blade, Arc Arcanum, and previous abilities from KH1 & KH2.
A New Combo Attack with Goofy!
There’s a lot more, but I’ll let the expert game analysis-es(?) handle it. I got work tomorrow.
