This week's update brings improvements to meteors, save games, and the in-game chat.
Meteors and meteoroids now have different particles. Meteoroids have a dusty debris effect as they travel through space, but as they enter an atmosphere (becoming meteors) the particle effects become more fiery and smokey. They now also create bigger and better looking craters on impact. Lastly, they have been balanced to target your structures less frequently and less accurately.
We’ve added the ability to backup saved games automatically. You can set the max amount of backups in the advanced world settings. The in-game chat feature has been improved by adding global chat history.
