There are six Copper Stars in Tenebris Somnia, and each opens one specific Star Locker for a reward. Complete every locker before the photo-development puzzle in the school, triggered after obtaining the red lightbulb; this is the point of no return and missed lockers cannot be recovered in that run. The locations below list each star's floor and container or event, then each locker's exact floor and container, so you can match stars to lockers as you find them.
Before You Start
- Obtain the red lightbulb first. The warning states that the school photo puzzle begins only after you fetch the lightbulb.
- Treat that moment as the last chance to backtrack for stars or lockers you may have missed.
- Carry any stars you already have so you can open lockers when you reach them.
- Remember the floor numbering used in the guide: Floor 0 is the lowest level mentioned.
Copper Star Locations
Copper Star 1
On Floor 3, go through the blue door to the street. The star is hidden in the trash can there.
Copper Star 2
On Floor 1, go through door 'A', then through the double glass doors. The star is visible on the floor in that area.
Copper Star 3
On Floor 0, search the plant near the elevator. The star is inside it.
Copper Star 4
After completing the copper seed puzzle, you reach a room that you illuminate using TVs. On the right side of that room is a shelf hiding a star.
Copper Star 5
After defeating the boss behind the cow skull door, check the drawers in the same room. The star is in the drawers.
Copper Star 6
On Floor 1, look for the red figure holding a green object at the top of the stairs. Once you obtain the chisel and return, the star will drop from his hand.
Star Locker Locations
| Locker | Location | Reward |
|---|---|---|

| 2 | Floor 2, Ivan's apartment, kitchen, top right cabinet. | Lavendoleum |
| 3 | Floor 1, through door 'B', in the bathroom where you can save, right cabinet. | Revolver ammo |
| 4 | Floor 1, through door 'A', upstairs near the projector, on the right shelf. | Lavendoleum |
| 5 | Floor 3, Ivan's apartment, the room locked by the green symbol, left closet. | Shotgun shells |
| 6 | Floor 0, through the glass door, through the emergency exit, up one set of stairs, through the door and next to it. | Revolver ammo |
Route Planning Tips
- Start with stars that are easy to reach early, such as Copper Star 2 on Floor 1 and Copper Star 3 on Floor 0 near the elevator.
- Use the locker table to plan a route by floor. For example, Floor 2 contains Lockers 1 and 2, so gather stars for those lockers before heading there.
- If you reach the director's room before having a star, note that Locker 1 can be revisited later, but do not rely on that for other lockers.
- After the copper seed puzzle and TV-lit room, grab Copper Star 4 before moving on.
- Defeat the cow skull boss and open the drawers for Copper Star 5, then use it on the nearby locker if you have not already opened it.
- Return to the red figure on Floor 1 with the chisel to make Copper Star 6 drop, then visit its locker.
Because some stars are tied to puzzle and boss progression, it is safest to clear all lockers as soon as you have the matching star. The achievement depends on opening all six before the red-lightbulb photo puzzle, so double-check each floor and container before advancing the story past that point.
