Walkthrough:Kingdom Hearts Re:coded/Destiny Islands

<!--- You are introduced to Bloxes by Selphie. Talk to her again to start a side quest and start destroying bloxes. Go to the west and find Wakka. He will ask you to destroy one special blox on the platforms. Do so to get a HP+2 chip and be introduced to types of bloxes. Install the chip in your Stat Matrix and report back to Wakka. He will ask you to find Tidus who is on the small island outshore. Jump above the hut to trigger a cutscene and then go to that wall where that man in black disappeared into to find a Backdoor. You'll be introduced to System Sectors and things related. Just defeat all the enemies.
