Edgewater isn't the only part of Terra 2 you'll explore in The Outer Worlds. During the game you will learn more about Roseway and have to complete certain missions there. During the Doom That Came To Roseway mission, you will have to explore a secret laboratory. As you do so, you will meet Cassandra, a character who got trapped in a cell.
It turns out that she has something that you need and that she might part with it if you help her out of her trap. To do this, you will need a key card. In this guide, we'll tell you where to find it.
The Outer Worlds - Doom That Vame To Roseway - Secret Lab Security Keycard Location
To find the map, you need to find a specific terminal to print it. Go to the location shown on the map above. Right next to Anton's canteen and office with the vault destroyed, there will be a locked door. Hack it and you will find the porter's office inside. The terminal inside will print the card for you.
You will need to have spoken to Anto and Cassandra for this to work, according to reports from some players. However, there is another way to get the key card. If you talk to Cassandra and have enough dialogue skills, you will be able to convince her to stop fighting with the lab security guards and let them go.
If you come back to the entrance of the lab, you can speak to the head of the security forces and convince him that he is made for better things than dying in an unnamed lab. He will then withdraw his troops and also give you his security card which will work at all doors, including the one that trapped Cassandra.
So there you have it, now you know how to get the Secret Lab Security Card and continue the Doom That Came To Roseway quest.
