Spaceflight Factory : Prologue: is an Automation and (moving) Base Building inspired by Factorio and Stardeus.
During this Prologue, you will focus only on crafting rockets and try to launch them correctly to Earth.

On a post-apocalyptic Earth, all cities and settlements have been ravaged by pollution and a hostile biosphere.
In a last hope to salvage Earth, a crew of the best astronauts have been sent to a remote planet to collect a mysterious ore capable of turning Earth's destiny.

You will have to build an assembly line with conveyor belts, factory(s), foundry(s), insertor(s)... while defending your base from nearby swarms of Zorglings and rebuild an industry capable of launching spacecrafts and sending the supplies back to Earth.

With this new hope, you will lead a colony of human remnants. Help them to survive, and expand/gather enough resources to leave Earth.. The game also includes some incremental/idle game mechanics.
