Stella Plena: find every Copper Star and open every Star Locker
On this page
You need to open all six Star Lockers, not just collect six Copper Stars. Finish the sweep after retrieving the red lightbulb and before developing the photograph. That earlier cutoff avoids the later Sanguis point of no return.

Set aside the darkroom step until the sweep is done
Chuck’s location guide warns that developing the photograph advances the route towards the cutoff. Renka names the Sanguis fight as the point of no return. For a safe collection order, stop as soon as you have fetched the red bulb and backtrack now. You do not gain anything by testing how late the last cabinet remains reachable.
The star numbers below are checklist labels, not a required pickup order. Spending one at a cabinet does not mean another numbered star must go into a matching numbered locker. Track opened cabinets separately from remaining currency.
Six Copper Star hiding places
- Floor 3 street: go outside through the blue door and inspect the trash can.
- Floor 1 screening room: use Door A and the double glass doors. Search the floor inside the screening room.
- Floor 0 elevator: inspect the plant beside the lift.
- TV-lit room after the Copper Seed puzzle: search the shelf on the right once the televisions illuminate the room.
- Fumus room: after the boss behind the Cow Skull door, inspect the drawers in that same room.
- Floor 1 staircase figure: return after getting the Chisel. The red figure holding a green object at the top of the stairs drops the star.
The last two finds depend on progression. If the stair figure has not dropped anything, revisit after collecting the Chisel rather than repeatedly interacting before that stage. For the drawer star, first make sure you are searching the room reached through the Cow Skull door.
Spend the stars at these six cabinets
| Location | Cabinet landmark | Reported contents |
|---|---|---|
| Floor 2 director’s office | Trophy cabinet on the right | Aqua Vitae |
| Floor 2 Ivan’s kitchen | Upper-right cabinet | Lavendoleum |
| Floor 1, Door B bathroom | Right cabinet in the room with a save point | Revolver ammo |
| Floor 1, Door A, upstairs projector room | Shelf on the right | Lavendoleum |
| Floor 3 Ivan’s green-symbol room | Left closet | Shotgun shells |
| Floor 0 emergency-exit route | Go through the glass door, emergency exit, up one flight and through the door; cabinet is beside it | Revolver ammo |
Six stars collected, achievement still missing?
Count opened cabinets first. A star sitting in your inventory has not satisfied a locker interaction. If you have no stars left, compare the six cabinet landmarks with your route notes rather than revisiting only the pickup spots. The temporary director’s-office closure is also easy to mistake for a permanently missed cabinet.
Reward names follow Chuck’s guide and its credited contributor; use the location list as the completion checklist. When all six are open, check the Steam achievement before returning to the photo-development sequence.
