Note: Sectors was a beta feature and is not available in the stable 1.0 version of Starbound. Instead, different types of planets have hazards that correspond to the type of star they revolve around, and the hazards are mitigated through the use of an EPP (Environmental Protection Pack), not armor.
I am now on my first gamma sector snow planet and now i need warmer clothes, so i dont freeze to death. I was on a snow planet in beta sectors before and did not need my warm clothes. So do snow planets get colder with higher tier sectors or was it a illusion somehow?
