Secret of the Oracle is the first chapter of the Goodbye, Galaxy duology — the entry point into id Software's second Commander Keen series, and the one that sets the entire story in motion.

Its eight Council Members have been kidnapped and scattered across the Shadowlands, and it's Custom cartridge, plug and play. Compatible: DS, DS Lite, 3DS.
