Walkthrough:Kingdom Hearts Re:coded/Olympus Coliseum

Following your success at Wonderland, you find your way to Olympus Coliseum, an arena where all the top heroes compete in battles. After Data-Sora and Mickey talk to each other, you begin Outside the Coliseum and you can now replay and revisit earlier worlds from a save point. The opening area is fairly empty and devoid of any treasure so you can go straight through the north door to enter the Vestibule.

Save your game before talking to the strange goat, Philoctetes in the centre of the room. As it turns out, the Coliseum is infested with bugs and the champion, Hercules, is missing after he tried to sort them out. Data-Sora quickly discovers the world's Keyhole and enters it to reach the Labyrinth. The gameplay has drastically changed to have turn-based combat but the game explains all of these new mechanics through shreds of wisdom.

You start at Layer 01, the first level. Go to the westwards room and pick up the scrap of paper that teaches you about battles and how to fight. A Shadow then attacks you so you can try out the new combat system then. After the battle, break through the wall of blocks north to get to the next room, which has a scrap of paper teaching you about the bug level. Basically, your aim is to reduce the gauge in the top-left corner below the white line and you do this by destroying Bug Blox and Heartless. Once you've demolished the wall, continue on to the next room, where you'll learn about combos and blocking. Although it can be tricky at first, you'll get used to having timely reactions in order to do combo attacks and block damage. If you proceed onto the next room, a cutscene involving Hades will play. Once it's over, read another scrap of wisdom and then reduce the bug level in the next room to level 1, revealing a Rare Prize Block that contains a Strength +1 and allowing entry to the room southward, which contains a Magic +1. Afterwards, go upwards to the large room in the north and midway, a cutscene involving Hercules will play. After a scrap of paper about layers, you are free to explore this highly bugged room. Reduce the bugs to level 1, break the Rare Prize Blox containing a HP +2 and then break a block to the far west to uncover the layer's exit point. Between this and the next layer, you'll have time in a Save Room where you can save the game and trade with the Moogle.

At the start of Layer 02, a quick cutscene will play and then you'll have to traverse a new section of the Labyrinth. Some pathways are blocked so go up the north path to the north-east room, where you'll learn about Licenses. Then, go to the southward room however you'll find it blocked. Return to the room you started in to meet up with Hercules, who can break down walls, and after he joins your party. A horde of Heartless attack so you can practise team combat. Now that you can break walls, go through to the south-east room, where a Lucky Strike is immediately available. Then, continue to the south-west room and destroy bugs and blocks to uncover the exit point. However before you leave, go to the large room to the east, take down the bugs, and then grab the Defense +1 chip. The Moogle in the next Save Room offers you a range of new types of licenses.
