I've never been one for realism, but it's always irked me that the Mojave Wasteland is meant to be a nuclear-scarred desert, yet clean water seems in plentiful supply. Water Overhaul is a comprehensive hardcore mod for everything relating to water, it's availability, and radiation.


Water Variety

Radiation-free water sources are now much more uncommon, with most sources having at least a low level of radiation. Swimming and wading in water also gives more RADs.

Water has been separated into five different tiers, including three new (optional) items. In order of desirability these are:

  • Purified Water and Clear Water (NEW),
  • Dirty Water,
  • Bad Water (NEW),
  • Terrible Water (NEW),
  • Irradiated Water.

The effects of water sources have been changed to be consistent with their bottled water counterparts at maximum survival skill. Therefore, bottled water is generally less effective, but you can take it with you.

Bottled Clean and Dirty Water items in loot have an optional chance to be randomly replaced with the different water types to increase variety, and also make Purified Water more scarce.

Universal Water Bottling

Water Overhaul includes an optional and highly compatible water bottling system. Whenever you consume a bottled item, you can receive a generic Empty Bottle item (which has a unique model courtesy of Jokerine). Likewise, picking up any empty bottle (Nuka Cola, Whiskey, etc) will replace it with one of these generic bottles too. When facing a water source you can press the Grab key to fill an Empty Bottle. Simple. This will work with any water source from any mod.

More Rads

By default, radiation on all consumables has been increased dramatically. In my opinion this greater improves the difficulty of Hardcore, as food and water radiation was hardly an issue in the vanilla game.

Water is more radioactive than most other food. This is for balance, since you can now 'create' water items by filling bottles at any source, and these bottles can be reused to your heart's content.

Consistent Recipes

In vanilla, some recipes produced bottled items even though they require no bottles or bottled items, and others produce less bottled items than they require. These bottles seem to be appearing and disappearing into thin air! Water Overhaul applies the simple concept of 'bottles in equals bottles out'; many recipes have been edited to require Empty Bottles, or produce spare ones accordingly. As an added extra, collecting Cloud Residue in Dead Money now requires you to use an Empty Bottle.

Famine Integration

Water Overhaul taps into Famine's item rarity system to prevent having to run similar scripts for certain features. You can also optionally increase the rarity of empty bottles to help balance the water bottling mechanic.
