Where to find the key code to Carter's PC in Directive 8020
Directive 8020 is filled with locked doors and computers you need passwords to access, and when you're trying to quickly make your way through a section without getting spotted, not knowing where to look for key codes can make tasks a lot harder. It's impossible to stand around and input thousands of potential passwords, especially when any number of alien lifeforms could get to you before you find the correct one. So it's best to spend that time searching for hints instead.
The key code to Carter's PC is one of the first you'll need to discover in Episode 2, and fortunately it's one of the more straightforward passwords to uncover. You only need four numbers, rather than having to string together an actual passcode, and once you know what clue to look out for, you'll be gaining access to his files in no time. Here's what you need to do.
Where to find the key code to Carter's PC in Directive 8020
The key code you need to unlock Carter's PC is 2808. You can also use 0828.
The clue is the post-it note stuck to the front of his monitor which states "Luna's" and has an arrow pointing toward the screen. If you leave Carter's room into Crew Quarters, and turn right, there's a calendar on the wall. Inspect this by walking up to it and pressing the left mouse button, and it'll show you the month of August.
On the 28th, "Luna's Birthday" is written in bold letters. So, take this date alongside the month, and input it into the computer. It doesn't matter if you do the date first or the month, as they both unlock the PC. Interact with the computer again, and a cutscene will then play showing Simms walking into Crew Quarters, and then a new objective will appear instructing you to follow her.
You won't be able to interact with Carter's PC a second time once this cutscene has played, it's basically only there to trigger the next cutscene with Simms and raise Eisele's suspicions. Follow Simms through Crew Quarters and into the Lounge, where you'll find her in front of the monitor showing a log of her and Carter talking, and you'll be able to continue the story from there.
