This is how to get survival. Follow these steps and it will get released.

Ok, step 1. Listen to the anthem of Scrap Mechanic. Here's the lyrics:
Rise, young mechanic!
It's time to celebrate!
Your magnificent creations,
built on sweat and tears
March, mighty farmbots!
March, further into space!
On a glorious mission,
To send the workers home!
Oh, mechanic, so creative!
He will serve us well!
Thanks to you, our great mechanic,
Food will come flying our way!

Think about the lyrics to that song. Think about the glory.
"Rise, young mechanic!
It's time to celebrate!
Your magnificent creations,
built on sweat and tears
March, mighty farmbots!
March, further into space!
On a glorious mission,
To send the workers home!
Oh, mechanic, so creative!
He will serve us well!
Thanks to you, our great mechanic,
Food will come flying our way!"

Ok, have those lyrics at hand. Open up Scrap Mechanic. Once it is open, create a new world. Set it to flat, add the mods you need for this (It depends, read the next step so that you know what mods you need.) and start!

Now, build what comes to mind when listening to the song. Build what it represents. Think about it. Do this until Scrap mechanic Survival is released.
