The Electronic Components are obtained by interacting with the ticket machine near the Hospital entrance.

### Other Collectibles

**Pro-Tip from GameJinn:** Always keep an eye out for glowing objects and use your Walkman’s scan function frequently. Many collectibles are small and easily missed in the detailed environments of *REPLACED*. Don’t be afraid to backtrack and explore every nook and cranny! And remember, some quests, like David’s and the Doctor’s, directly lead to unlocking multiple collectibles, so prioritize those!

Now go forth, gamer, and collect ’em all! And if you have any more questions about *REPLACED* or any other game, you know who to ask!
