Although Kingdom Hearts 3 launched with around 10 Keyblades available in the game (counting certain bonus Keyblades), many fans missed some of the classics. This includes weapons such as the Oathkeeper and Oblivion, and while they're not available to be equipped by Sora, there are other unused Keyblades that can be unlocked via a particular method.
These Keyblades appear in the game, but are used by other Keyblade wielders. Some even appeared in Kingdom Hearts 3 cut scenes where it seems they could be used, but that proved to not be the case. These weapons are the Master's Defender, Kingdom Key D, Mickey's Keyblade, Way to Dawn, and Braveheart, all of which can be unlocked by using Save Wizard for PS4 Max.
To do so, Kingdom Hearts 3 players must insert the appropriate code into the three slot offsets: Slot 1 offset 1878, slot 2 offset 1880, and slot 3 offset 1888. The codes for each of these weapons are as follows:
- Master's Defender, 033d
- Kingdom Key D, 0342
- KH3 Mickey's Keyblade, 0343
- Way to Dawn, 034f
- Braveheart, 0350
Luckily, for those who do not want to mess with this PS4 Max approach, there is a video showcasing these unused Keyblades. There doesn't appear to be anything special about any of these Keyblades in combat, likely because there were never intended to be wielded by Sora.
So, anyone who uses this method may only be unlocking them for some character flavor for their Kingdom Hearts 3 playthrough. It's also worth mentioning that, since we know Kingdom Hearts 3 is receiving some form of DLC, these weapons or the aforementioned Oathkeeper and Oblivion could be officially added as part of new content.
Considering that DLC is on the way, the addition of new Keyblade and Keyblade forms seems likely, but it's also possible this "new" content isn't exactly new. Recent speculation has suggested that some cut content could be returning to Kingdom Hearts 3 as downloadable content, but until something official is confirmed by Square Enix, we recommend taking that news with a healthy dose of salt.
Kingdom Hearts 3 is out now for PS4 and Xbox One.
