Like previous games, Pokémon Super Mystery Dungeon allows you to rescue friends when they're defeated in dungeons.
There are 4 methods to send/receive codes:
- Password
- QR Code
- Local Wireless
- IR Connection
Unlike previous games, rescues are region-locked. Only US games can perform US rescues, only European games can perform European rescues, etc. Recent discoveries have made it possible to convert US rescue passwords to and from European rescue passwords. A tool to do such conversion can be found here.
