I'm trying to be positive about this, but I really don't get some of the criticism surrounding Survival mode.
At the start I get it. I walked for 5 minutes on a freezing cold planet to find my ship and got taking in by the new patch. I never realized - because I had no idea how the systems worked - what was happening to my health and life support. This is a hangover from the original game, where we had become complacent. You could just recharge everything easily. No need for upgrades or more slots in your suit, just walk over there for a second and recharge everything with just a couple of elements. I don't know why anyone would have expected that then, let alone now in a Survival mode?
I just wasn't prepared for what I had to do. Before, the only real need to upgrade my protection or life support was on a very extreme planet, but even then it was easy to recharge everything. Now, you actually have to think about whether you can even land on a planet. And why shouldn't you? A ship's slot can carry 500 of an element. Two slots can carry 1000 Plutonium. That's 5 take offs. Taking off is now a responsibility. It's tough at the start, yes, but surely that was the wake up call? It was to me. That's when I realized, "If I don't have the Plutonium to lift back off, then I shouldn't be landing at all". That's down to me.
But what happens when you land on a planet? Again, if I don't have the required elements, then I need to find them first. Thamium9 is number 2 on the list of most important elements. It maybe harder to mine Iron in space to fuel your Pulse drive, but you only need 50 Thamium9 to recharge your life support and it's out there. Two slots of an exo suit hold 10 recharges. If you don't have any of that then you're back to the Plutonium mixed with Carbon. I haven't even upgraded any of the systems required for on-foot, but I know that if I prepare my inventory before hand, I'll be fine. So I'll be even more fine when I find the upgrades for life support. Those upgrades that never made any sense before, are you sure they won't make it a hell of a lot easier now? That's where we've become complacent. I installed those upgrades and never saw the point, so I forgot about them, but they are probably integral to how you move about in this mode. Not forgetting the increased importance of linking upgrades together.
Not all planets are going to be devoid of the 4 elements you really need, so stock up. What I do is divide them between my suit and ship. That way, if i die, at least I have enough resources to carry on.
