In Metroid Prime 3: Corruption, Samus Aran encounters a small PDA when in the Control Room of the G.F.S. Valhalla. Scanning it will state that the model is commonly used by multiple personnel within the Galactic Federation. The PDA is malfunctioning as it is flickering a code, the most likely reason for the malfunction is the fall of the Federation Marine that is just beside it. The Access Code, 78356, can be entered into a nearby Key Code terminal to access a secret message from Aurora Unit 313. This message will earn Samus a Friend Voucher.
"This model of PDA is commonly used by many Federation personnel. The current display reads: 78356."
