New Update: Planets have been released.
There is so much to cover but I will give a short list of highlights, and as usual you can see the update here:
http://forum.keenswh.com/threads/update-01-108-planets.7372785/Planets are not generated in worlds and are instead placed manualy, or by default based on your starting world.
There are new starting maps including Easy Starts for various planet types.
Sabaroid bug-like aliens will now spawn on certain planets and are highly agressive.
Pirate bases spawn randomly on planets, and players will be attacked by Pirate Drones from time to time.
Atmospheric thrusters are now in the game. These thrusters are powerful, but only work within an atmosphere.
Small ships now have oxygen vents.
And more. Have an enjoyable engineering, guys.
