System Sector

'System Sectors are locations unique to ''Kingdom Hearts Re:coded. They can be accesed through Backdoors, and are found in every world. A System Sector can have several different floors. Once one floor is cleared, a transport appears, allowing Sora to move up a floor. Eventually, a terminal will open, allowing Sora to leave the Sector altogether.

Inside each Sector reside bugs. If a section of the Sector is colored red, enemies must be eliminated. Once Sora has defeated enough Heartless, the room will become blue. Defeating Heartless and destroying Blox will earn Sora System Points, or SP. Once the Sora leaves the Sector, he will be prompted to redeem his SP for rewards. The first few rewards will be highlighted in yellow, meaning that they are "system rewards", and that they can only be redeemed once. Below these are other prizes, which can be obtained repeatedly. Once the player doesn't have enough SP for an item, they can trade the remainder in for equivilant EXP or munny.

After completing Traverse Town, System Challenges become available. Once Sora enters a System Sector, he will be rewarded 1000 SP. Before he can enter each floor, he will be prompted to wager 10, 30, or 50 percent of the 1000. If he can complete the challenge, he will be rewarded the amount wagered, with a multiplier added. The same will occur if he loses the challenge. If the player runs out of HP during a challenge, they lose a large majority of their SP. Each floor has a separate challenge.
