This achievement is choosing to escape the planet with the Smugglers ending.
To Unlock any of the endings, you need to build a "Large Explosive Device" under the Warden Sphere in the superalloy cave. This unlocks the ability to use the "Extraction Platform".
The smuggler's ending requires you to receive all the messages from Riley, amass 500,000 terra tokens and put 5 Solar Quartz in the extraction platform.
