How to Play Kingdom Hearts: Chain of Memories
Quick start
Select "NEW GAME" and enter Castle Oblivion with Sora. On the first floor, use the map cards at the door to create a room, defeat Heartless and collect new cards as you aim for the event room where the story progresses. In battle, check the numbers and order of the cards, and be careful not to hit the same card repeatedly and immediately go into reload mode. You can save at save points between floors, and if you want to finish midway, you can also use "Quick Save" in the menu.
Controls
In the field, use the cross keys to move, A to attack/inspect/speak with the keyblade, B to jump, START to open the menu, and SELECT to open the world map. In battle, use the selected card with A, jump with B, switch the card reel with L/R, change the card type with SELECT, and pause with START. Stock cards with L+R, collect 3 cards and press L+R again to activate the stock technique. Holding A on a reload card refills the deck.
