Command Matrix

The Command Matrix (コマンドマトリックス) is the command system in Kingdom Hearts Re:coded. Before deck commands can be used in battle and in the field, they need to be installed in the Command Matrix.

The commands that can be installed are limited by the amount of Memory each command takes up and the number of available slot groups in the Command Deck. Three slot groups are available initially, with up to five additional slot groups that can be unlocked by hooking up chips to Command Expansions in the Stat Matrix.

Command Conversion
A slot group consists of two blue slots and one red slot. If commands are installed in the two blue slots, they will be "test-converted" into a new command, which appears in the red slot and the Command Deck. If the two blue slots are filled with compatible commands, indicated by a yellow highlight in the selection menu, the red slot will contain a wholly different command; otherwise the red slot will simply contain a stronger version of the command in the first blue slot.

Defeating enemies earns Command Points (CP) for all installed commands. When a command accumulates enough CP, it is marked with an exclamation point. When two marked commands are installed in adjacent blue slots, they can be permanently converted into the command that appears in the red slot. The converted command may receive an additional bonus, called an  Overspec: it may gain extra levels, it may fill the Clock gauge more quickly, or it may have a faster reload time. In the latter two cases, the command will be marked with a   or   symbol, respectively, next to its name. If a command has received both bonuses, it will be marked with a   symbol.

Commands can be converted over and over, but no command can exceed a maximum level of 100. Some commands can only be obtained through Command Conversion.

Overlay commands
Overlay commands are abilities that only appear in the rail-shooting and side-scrolling areas of Traverse Town, Wonderland, and Hollow Bastion. They are in place of the normal Deck Commands, and have limited number of uses.
