- Now the inner solar system has voiceover throughout (including the comet and sun level)! The space slugs that have been found in the inner solar system can now speak their names that you the community have named them. If you find the ghost, you can hear a special message from it as well... but be quick, the ghost will disappear at the end of October! It will only show itself in October, so if you miss it this year, you can find it next year!
- Hurry up and try to find the spooky secrets as well! If you find any secret in the game, screen shot it with F12 and share it to the Planetary Settlers Community Page here on Steam. This event also ends the end of the month.
- There are still space slugs in the outer solar system (Jupiter, Saturn, Uranus, and Neptune) to be found. One may be coming to Pluto later. If you find a new one, you get to name it, and it will be able to speak the name you give it! They can't speak yet until you name them.
- I plan to work on voiceover for the outer solar system next.
