The necessities in NEO Scavenger are food, drink, and warmth. When you’re first starting out, you can’t be picky about what you wear. If it’s clothing that covers a part of your body, put it on. For food and drink, you can be more selective. You begin sated, and not all food and drinks are safe. Carry whatever you find but wait until you can boil the water to consume it, unless you have no other choice.
