Volatile Fuels & Fires

A unified, overhauled, and rebalanced mod for Factorio 2.1, with full Space Age support.

This mod combines and expands mechanics inspired by Flammable Oils Continued and Explosive Fuels, introducing dangerous fire and explosion mechanics for fluids, solid fuels, explosives, and nuclear materials.

Your factory is no longer just a production facility — it can become a chain of devastating explosions.

Key Features

1. Flammable Fluids & Infrastructure

Pipes, underground pipes, pumps, storage tanks, and fluid wagons can catch fire and explode when destroyed.
Production buildings containing flammable fluids are also vulnerable.
Explosion strength depends on the total energy stored in an entity's fluidboxes.
Fires and explosions can trigger devastating chain reactions.
Configurable ignition chances, explosion damage, radius, delays, and pollution.
Space Age non-flammable fluids are excluded by default.

2. Combustible Solid Items

Wood, coal, carbon, sulfur, solid fuel, and selected Gleba organic materials can catch fire.
Fires can spread across transport belts, dropped items, and destroyed cargo containers.
Filled fluid barrels inherit the flammability and energy properties of their contents.
Solid fuel burns intensely but does not detonate.
Coal and sulfur fires generate additional pollution.

3. Explosives & Ammunition

Explosives, grenades, cluster grenades, rockets, flamethrower ammunition, cannon shells, and artillery shells can detonate when exposed to fire.
Explosions can ignite nearby flammable objects and trigger chain reactions.

4. Four-Tier Fuel Detonation System

Rocket Fuel, Nuclear Fuel, and Atomic Bombs feature four configurable detonation tiers based on the quantity of items stored in an entity.

Rocket Fuel
- Tier 1: 1–9 items
- Tier 2: 10–19 items
- Tier 3: 20–59 items
- Tier 4: 60+ items

Nuclear Fuel
- Tier 1: 1 item
- Tier 2: 2 items
- Tier 3: 3–5 items
- Tier 4: 6+ items

Atomic Bombs
- Tier 1: 1 item
- Tier 2: 2–4 items
- Tier 3: 5–9 items
- Tier 4: 10+ items

Higher tiers produce increasingly powerful explosions. Nuclear Fuel and Atomic Bombs require entity destruction or a nearby blast to detonate; ordinary fire alone is not sufficient.

5. Dynamic Tooltips & Customization

Item descriptions automatically display detonation tier thresholds.
Tooltip values update when the corresponding startup settings are changed.
Configurable explosion parameters and ignition behavior.
Support for custom fluids and modded content through remote interfaces.
Bounded processing queues help maintain performance during large-scale chain reactions.

Compatibility

Factorio 2.1
Space Age (optional)
Vanilla fluids and supported modded fluids.
Modded fuels and compatible custom content.

Important: This mod is incompatible with the following original mods and forks because they share overlapping prototypes and mechanics:
- Flammable Oils
- Flammable Oils_QUICKFIX
- Flammable Oils Continued
- Explosive Fuels

Do not enable these mods alongside Volatile Fuels & Fires.
