Discover the new liquid system in Dead Rails Roblox, how to collect, use and combine different liquids to boost your gameplay.

Liquids have splashed into Dead Rails, and they change more than the color of your boots. Puddles sit across every map, coating anyone brave or careless enough to step through them. Pick up a bottle, scoop up the mess, and you suddenly control elemental tools that can heal, ignite, or brew potions with teeth.
Water is tame, kerosene is trouble, and unicorn blood is pure jackpot. Because every droplet carries a purpose, knowing what it does and where it hides is a new survival skill. This guide strips the feature down to bare essentials so you can turn puddles into power.
Liquids in Dead Rails Roblox
The liquid system in Dead Rails is easy to understand but packed with potential. Liquids form puddles on the ground. Step into a puddle and your character gets covered. You’ll see a prompt showing which liquid you’re soaked in. This isn’t just cosmetic—different liquids have different effects.

To collect any liquid, grab a Glass Bottle while looting buildings. Pour two liquids into the same puddle to mix them and possibly create new effects. This system becomes especially useful for crafting advanced items or creating environmental hazards.
Currently, six liquids exist in the game. Here’s a breakdown of each, including how to get them and what they’re used for:
Liquid Type | Appearance | Source | Uses |
---|---|---|---|
Water | Pale blue | Drops from the sky as rain | Used to craft Holy Water |
Blood | Dark red | Leaks from damaged non-zombie, non-unicorn creatures | Ingredient for Angel Tears |
Zombie Blood | Murky dark green | Leaks from zombies when damaged | Unique to zombies, no crafting use listed yet |
Milk | White | Comes with the Milkman class | Ingredient in Primordial Soup |
Kerosene | Yellow | Falls as rain in Scorched Earth zones | Makes things flammable, used in Molotovs and Devil Tears |
Unicorn Blood | Bright magenta | Comes from damaged unicorns or lightning-struck puddles | Base ingredient for most potions |
You can mix these liquids freely, but be cautious. For example, soaking someone in kerosene makes them highly flammable, while covering yourself in unicorn blood might be necessary for certain potion effects.
Use puddles tactically. Turn weather events like rain or lightning into opportunities. Loot Glass Bottles when possible. And don’t ignore those strangely colored puddles, they might be more useful than they look.
