Came but to NMS after about 2 years off. Played a new permadeath game with a friend, no other options changed from normal. But I couldn't last more than a few minutes.
Had to sprint to ferrus, I had to sprint to sodium, and even then I died about 50% of the time. Three sodium plants got me to maybe 30% hazard protection. My hazard protection was ticking down at 1% per second. Falling from any height (even jetpack softened) meant my jetpack broke.
And after four attempts, I finally got the ship and recharged to max with a good ten harvested sodium plants before going off on the Hermetic Seal quest. Half way there, the game throws a storm at me. Totally open ground, no shelter at all. And my entire stock of Sodium goes in seconds and then I die.
My friend's hazard protection was going down a lot slower, even when we were next to each other and his sodium filled him up a lot more (he said about 50 to full, I needed over 100 to full).
No idea what I did wrong.
