The code for Carter's PC in Directive 8020 is 2808 (or 0828 if you enter month-first). This puzzle appears early in Episode 2, "Sleuth", while you're controlling Eisele and searching for the missing sleep crew. The terminal sits on Carter's desk, and both clues you need are right there in the same cabin. No guesswork, no trial and error.
What is the code for Carter's PC in Directive 8020?
The passcode is 2808. You can also type 0828 and the terminal accepts either format, since the game allows day-month or month-day entry. Both unlock the screen and move the story forward.
The code stays the same across all playthroughs. It's hardcoded, so if you're replaying Episode 2 for a different outcome, you can walk straight to the terminal without checking the clues again.
Where to find the clues in Carter's cabin
Supermassive Games placed two environmental details in Carter's quarters aboard the Cassiopeia. Neither is particularly hidden, but the cabin's dim lighting means players who rush through the room miss both.
Step 1: Read the sticky note on the monitor
Walk up to Carter's locked PC and look at the monitor. There's a sticky note stuck to the front with the word "Luna's" and an arrow pointing at the screen. That's your only hint. You need to find something in the room tied to that name.
Step 2: Find the calendar in the living area
Turn away from the desk and walk into the main living area of Carter's cabin. Scan the walls until you see a physical calendar hanging up. Interact with it to zoom in. The calendar shows August, and the 28th has "Luna's Birthday" marked in bold. August 28 gives you the digits: 2808 (day-month) or 0828 (month-day).
Both formats work on the terminal.
Step 3: Enter the code at the terminal
Head back to Carter's desk and interact with the keypad. Type the 4 digits and confirm. If you're using a controller with high sensitivity, wait for the audio cue after each digit before moving to the next. Rushing the input can reset the entry screen, which players have reported since launch.
- Walk up to Carter's locked PC
- Interact with the keypad prompt
- Enter 2808 (or 0828)
- Confirm the entry
Once the screen unlocks, Eisele accesses Carter's files. A cutscene plays showing Simms entering Crew Quarters. After that, you get a new objective to follow her. The terminal becomes non-interactive at this point, so you can't go back to recheck the files.
Clue locations at a glance
What happens after you unlock Carter's PC?
Accessing the terminal reveals files about the sleep crew's strange behavior, giving Eisele the narrative context she needs for the next section. After the unlock, follow Simms through Crew Quarters and into the Lounge, where you'll find her standing in front of a monitor showing a recorded log of her and Carter talking. That's where the story picks up.
Skipping this terminal is technically possible since the game doesn't force you to interact with it. But players who skip it miss the setup for the stealth section that follows. The terminal is also a required step for the Full Truth achievement path, which tracks every hidden document and terminal entry across the full game. Miss it here and that achievement is locked out for the entire save file.
Is this puzzle missable?
Yes. Once you trigger the main sequence and leave Crew Quarters, the door locks. There's no chapter select mid-playthrough that brings you back to this specific moment. If you're aiming for 100% completion, treat Carter's PC as mandatory regardless of what the game technically allows.
