You can find the Silo Access Badge sitting in the upper section of the shop where Mel stays. Another important item is the Old-Fashioned Key, which you can pick up only after you beat the boss named Calderon.

If you are looking for the Bell Tower Visitor Pass, head to the very top of that area and follow the single path available to you in MIO: Memories in Orbit.

Boss Rewards and Seals

After your fight with Sol & Vin, move forward and climb to the highest part of the area before you get on the elevator. Once you reach the top, walk to the right to find Lura’s Seal.

Similarly, once you take down the boss Flora, look behind the spot where the fight happened. Head to the right to grab the Aviaries Passepartout.

Hidden Invitations and Ledgers

To get the Friendly Invitation, you need to use the hairpin and follow the only path forward. For Dr. Halyn Key, go down to the bottom of the area and navigate through the lasers and crates.

At the end of the path, look for Dr. Halyn's Employment Ledger and interact with it to get the key in MIO: Memories in Orbit.
