The code for Carter's PC in Directive 8020 is 2808 (or 0828 if you prefer month-first). This puzzle shows up early in Episode 2, "Sleuth", when you're playing as Eisele and tracking down the missing sleep crew. The terminal sits right on Carter's desk, and the answer is hiding in plain sight in the same cabin. Two clues, one code, no guesswork required.
What is the code for Carter's PC in Directive 8020?
The passcode is 2808. You can also enter 0828 and the terminal will accept it either way, since the game lets you input the date before or after the month. Both combinations unlock the screen and trigger the next story beat.
The code never changes between playthroughs. The passcode is static, so if you're replaying Episode 2 for a different outcome you can skip straight to the terminal without hunting the clues again.
Don't interact with the main hallway door before unlocking the PC. Triggering that door starts a point-of-no-return cutscene and locks you out of the terminal permanently for that playthrough.
Where to find the clues in Carter's cabin
Supermassive Games built this puzzle around two environmental details in Carter's personal quarters aboard the Cassiopeia. Neither clue is especially hidden, but the dark lighting in the cabin means players who rush through miss both of them.
Step 1: Read the sticky note on the monitor
Walk up to Carter's locked PC and look at the front of the monitor. There's a sticky note with the word "Luna's" written on it, with an arrow pointing at the screen. That single word is your entire lead. You need to find something in the room connected to that name.
Step 2: Find the calendar in the living area
Turn away from the desk and walk out into the main living area of Carter's cabin. Scan the walls until you spot a physical calendar hanging up. Interact with it to pull focus. The calendar shows August, and the 28th has "Luna's Birthday" written in bold. August 28 gives you the digits: 2808 (day then month) or 0828 (month then day).
Both input orders work on the terminal.
Step 3: Enter the code at the terminal
Head back to Carter's desk and interact with the keypad. Type in the 4 digits and confirm. If you're on a controller with high sensitivity, wait for the audio confirmation cue after each digit before moving to the next. Rushing the input can reset the entry screen, as noted in community reports around the game's launch.
- Approach Carter's locked PC
- Interact with the keypad prompt
- Enter 2808 (or 0828)
- Confirm the entry
Once the screen unlocks, Eisele gains access to Carter's files. A cutscene then plays showing Simms entering Crew Quarters. After that, you'll receive a new objective to follow her. The terminal becomes non-interactive after this point, so there's no going back to recheck the files.
You cannot return to Carter's PC after the Simms cutscene triggers. The door to Crew Quarters locks behind you. Grab anything you need from the room before entering the code.
Clue locations at a glance
What happens after you unlock Carter's PC?
Accessing the terminal reveals files tied to the strange behavior of the sleep crew, giving Eisele the narrative context she needs heading into 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 displaying a recorded log of her and Carter talking. That's where the story continues.
Skipping this terminal is technically possible since the game doesn't force you to interact with it. But players who skip it miss the contextual setup for the stealth section that follows. Community reports also indicate the terminal is 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.
The ALLPOSSIBLEFUTURES achievement is currently sitting at 0% completion on Steam according to data cited at launch, which gives you a sense of how demanding the full completionist path is. Carter's PC is step one.
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.
