For This One, You Just Have To Decrease A Lava Planet's Temperature To Zero Celsius, With A Terraformer.
- Try Sending Nuggetoids, (Robots) So You Dont Have To Worry About Your Villagers Bursting Into Flames.
- Nuggetoids Can Recharge Each Other With The Right Technology
You Will Need:
- Fuel And Chemicals To Run The Terraformer. (Probably Use Trade To Ship Them In)
- A Water Tower And A Solar Panel To Run The Terraformer.
- Patience. (Or A Second Terraformer)
Achievement Pops As Soon As The Temp Hits Zero.
Good Luck!
