In this game we have all we ever wanted in a KH game: Co-op,Multiplayer Fighting, and Roxas gameplay. Got it memorized?
Gameplay: We get the normal Kingdom Hearts fighting, running into a horde of enemies and coming out clean, but Square Enix decided to put more rpg elements in using status effects. To the bosses there are strategies, you can't just go and slay the beast like in it's prequels. In story mode you play as Roxas, wielding only the keyblade, but they added a weapon customize for more freedom.
Mission mode: You can jump in and play as any character you unlocked in any mission you've unlocked. If you get stuck on a mission, try asking a friend to help you in co-op mode. In co-op you can fight each other just for fun, or you can complete the missions.
Other: Overall the graphics dont push the ds to the ends of the earth, but are average for a ds game. This game is rather pricey, but dont worry, you're getting your moneys worth. I give it a 8.5/10, or a 4/5.
