Thirst is one of the attributes that relate to your overall Survival in the game Planet Nomads. Being hydrated is similar to being well fed – you don’t lose stamina and regenerate health. Conversely, thirst increases stamina drain. Good hydration affects your thermoregulation and helps combat the negative effects of unsuitable temperatures. Water can be found in various locations on the planet. To collect (dirty) water press the action key when indicated.
However, water needs to be purified to be usable. Purified water can be made using a powered Compact FAD machine from dirty water and herbs. Herbs can sometimes be found by lasering the orange spiky plants which give you biomass also.
