So in the unstable releases all sectors have been merged, and tiers are separated by hazard requirements (Breath->Radiation->Cold->Heat, if I recall correctly). Currently, going to a radioactive/hot/cold planet gives a damaging debuff. I propose that this is changed, implementing everything as a bar which fills up, like breath. This means that certain blocks or locations could be dangerous to access before unlocking that tiers skin, or exist within a different tier. For example, in a Fiery system you are using the Heat skin and come across some radioactive fluid. Standing near it causes the Radiation bar to appear, meaning that you need to get away from it before it fills up and starts damaging you. Or on a radioactive planet you come across a crashed spaceship dungeon. The engine coolant has leaked into the ship, forcing the player to navigate around freezing pools to get to the security systems and control room to drain the freezing fluid, making the loot room accessible. I also think that Breath protection should be removed from Radiation, Heat and Cold, as it makes moons and liquids easy to navigate once you get the first skin. Instead, once you unlock a tier you should be able to complete a quest line to get a back armor which grants immunity to that specific hazard, but has a percentage energy penalty (20% slower energy regeneration?). You can also craft consumable items which fill up the bar, then provide a debuff similar to food. The consumables may also be purchased at the outpost, once you get the skin. With implementation of countering equipment, the possibility of dual effect planets comes into play, such as planets which have radioactive days and freezing nights, or are hot and have no atmosphere, making them more dangerous than usual. There could even be triple hazard planets, requiring countering blocks or consumable items to survive.
