Eidos 9 is the secret region of Stellar Blade. Playing through the main story without looking for collectibles will give you either the neutral or bad ending of Stellar Blade. You must reach 100 percent with Lily Artemis (the Engineer) by finding discoveries (collectibles) to unlock Eidos 9 and gain access to the best ending in Stellar Blade.

You can increase your relationship with Lily by finding data, passcodes, and documents. The only real way to watch your progress with Lily is when her icon appears in the top-right corner of the screen, after making a discovery. The white icon of Lily’s head with a rising percentage next to it only appears briefly and disappears a few seconds after your discovery. The bar and Lily’s head then reappear when you find something new. You can track your collectible progress via the Data Bank in the menu. 

Discoveries count as:

Data BankNumber of items to discoverDescription
Memorystick164Legionnaire and NPC memories, often found on bodies in hostile regions.
Log Data11Data often found on terminal and maintenance bots.
Journal12Diary entries.
Messages13Relating to side quests or found while exploring Naytiba-controlled regions.
AnnouncementsFourIncredibly limited collectibles, relating to region entrances.
Series27Books you can discover via bookshelves.
Promotions18Posters.
PrayersSevenChapter of Trial needed for the Recruit Passcode Specialists Request.

You don’t have to fully complete the Data Bank, however. Lily’s progress bar increases by point nine percent per discovery. You can easily reach 100 percent with Lily around the halfway mark in Stellar Blade‘s main story (Great Desert region). Focus on Bulletin Board Requests as these typically offer new information, context, and insight into the apocalyptic Earth, increasing your affinity with Lily. Not all requests increase Lily’s progress bar, though. Focus on requests that specifically ask you to find information.

Write down your current progress when Lily’s bar pops up, this way you know how far along you are. The bar will no longer appear once you reach 100 percent. It is highly unlikely you will find all Memorysticks before reaching 100 percent. Therefore, watch Lily’s progress bar whenever you pick up a new Memorystick as the bar won’t appear if you have reached 100 percent.

Going to Spire 4 (canon) or visiting the secret Eidos 9 (depending on your progress with Lily) count as the point of no return in Stellar Blade. So make sure to complete everything Stellar Blade has to offer before you go running ahead to enjoy the secret level, knowing that the best ending is right around the corner. Bullet Board Requests, NPC missions, Cans, encrypted caches, Robot spawns, and fishing are locked upon heading to Spire 4 or Eidos 9.
