Out of the airlock

How did you manage to get this achievement and how long/how often did you try?

[Stonehammers]

I got it trying to get the mutiny one. Somehow ended up throwing DeeDee out of the airlock instead of me. Was still given the achievement.

You have to feed only yourself until your mates starve. They will try to kill you and you have to defend yourself, then you get the option to throw someone out the airlock. then you get the achievement

Easiest way to do so is to have the captain well-fed and two or more crewmates starving on the same day. Feed the crewmates to get a mutiny event the next day, you'll be given item choices, but trust me don't do anything. The next day everybody will calm down and you'll be given the option to kick someone out the shuttle.
