extending the med bay

[theinkyisles]

im on week 18 and i am STRUGGLING (probably gonna have to restart the game at some point but im ignoring the reality of that). i read somewhere on a discussion thread that you can extend the med bay to fit 4 people at once but i have zero clue how im able to do that. any help is appreciated!

There was an upgrade you could find in the ship back in the day. On day 5 you can open several rooms in the ship. I searched through all the upgrades in the "normal" gamemode and I think this upgrade doesn't exist anymore.
I guess it was replaced with an upgrade that lets you produce "Medical Comforts" with only 2 scientists instead of 3.
Medical Comforts will heal all the people you put in your medbay instantly. So with this upgrade you only break even with investment with 2 medbay slots; making it feeling a bit underwhelming.

I think the other way to get another slot is through specialising the stowaway Runt into a medic. But I'm unsure, as I'm not there yet, trying to survive my early days right now :D
