</>What does No Survival Needs do?
Casualties: Unknown asks you to watch a lot of bars at once. Food and water run down, energy drains until you have to sleep, stamina runs out mid-climb, cold layers chill you, water cuts off your air and a bad mood slows everything down. No Survival Needs lets you take any of those off your plate, one at a time. Each switch holds one need at full while it is on. No Hunger and No Thirst keep food and water at 100, without the over-full penalties. No Tiredness keeps energy at 100. Unlimited Stamina keeps stamina at 100. Stable Body Temperature holds you at a normal 37 degrees. Unlimited Oxygen keeps blood oxygen at 100, so you can stay underwater, and stops pressure sickness on the deepest layers. Always Happy keeps your mood at the top even while you are hurt. The switches only change your own character, only during a run. Turn one off and that need runs down normally again from where it is. Injuries, bleeding, infection and other harm still work as usual.
</>What is No Survival Needs?
This mod lets you switch off the survival needs of Casualties: Unknown one at a time. Keep exploring without stopping to eat, drink or sleep, swim through flooded caves without running out of air, and stay warm on cold layers. Wounds and other harm still work as normal, so the medical side of the game stays the same.
</>Common questions about No Survival Needs
Can I turn on only some of the needs?
You can turn on any mix of the seven needs, because each one has its own switch and none of them depends on another. Turn on only No Thirst, for example, and food, sleep, stamina, body temperature, oxygen and mood all keep working the way the game normally runs them.
Can I still sleep with No Tiredness on?
Usually you cannot, because the game only lets you lie down to sleep when your energy is low, unless you take sleeping pills, and this switch keeps your energy full the whole time. If you want to sleep through a night, turn No Tiredness off first and let your energy drop.
What happens when I turn a switch off?
That need starts running down again from full, the same as after a meal, a drink or a good sleep, so you have time before it matters. Nothing else in your run changes, and you can turn the switch back on at any time.
Does this stop injuries or bleeding?
It does not, because this mod only covers food, water, energy, stamina, body temperature, oxygen and mood. Wounds, broken bones, dislocations, bleeding, infection, sickness and radiation still work exactly as normal, so you still need bandages, splints and medicine to stay alive on the deeper layers. Some of those needs do touch your health in the game: going without food wastes your muscles, thirst lowers your blood pressure, and low oxygen or extreme cold can stop your heart. With the matching switch on, those particular effects stay away, while every other kind of harm still reaches you.
Does Always Happy also cover pain?
Always Happy keeps your mood at the top even while you are in pain, bleeding or sick, so the low mood effects never kick in. The pain itself and what it does to your body, such as slowing you down or knocking you out, still work as normal.
Is a run saved with full needs?
If you save at the end of a layer while a switch is on, that need is saved at full, just like after a meal or a sleep. The mod does not use the developer console, so your save is not flagged and achievements keep working while you play with it.
