CBC : Nuclear Cannons

CBC: Nuclear Cannons

CBC: Nuclear Cannons expands Create: Big Cannons with nuclear artillery and the long-term consequences of using it. It adds three shell types—fission, thermonuclear fusion, and radiological dirty bomb—along with a persistent radiation system, protective equipment, and post-blast contamination.

Built for Minecraft 1.20.1 / Forge. Requires Create: Big Cannons.

The Three Shells

Fission and fusion shells carve massive ray-traced craters, produce mushroom clouds, and leave lasting fallout. The fusion shell is larger and more destructive, with a taller cloud and heavier contamination. The dirty bomb is not a budget nuke: it barely damages terrain and creates only a low-yield contamination cloud. It is meant to make ground dangerous to cross, not to erase a base.

Fission and fusion shells are deliberately expensive. They sit at the end of the uranium enrichment chain, behind advanced processing and specialized components. The dirty bomb is cheaper but limited, and it exists to force a response—not to replace proper nuclear weapons.

Detonations and Fallout

A detonation combines an immediate blast with a much larger ray-traced crater processed over several ticks, so it does not freeze the server. Craters are layered, with vitrified slag, scorched soil, and charred materials. Overhangs may collapse.

Nearby clients see a screen flash, camera shake, and a custom mushroom cloud. Contamination is spread through both the convection column and the ground, so the cloud and crater remain hazardous after the initial explosion. Afterwards, the area may be affected by a fallout zone, a diffusing contamination cloud, and surface fallout.

Radiation and Protection

Radiation is tracked per entity as an absorbed dose. The environment adds dose over time; the body and medical items remove it. Only the accumulated total matters, and it persists until treated or cleared by death.

Dose can come from radioactive blocks in the surrounding area, carried radioactive items, dropped radioactive items, open-air fallout, and surface contamination. Protective gear and containment matter.

The Radiation-Safe Canister shields radioactive contents while carried. The anti-radiation suit reduces ambient exposure piece by piece, with the full set offering the best protection. It does not protect against the instantaneous flash of a nuclear detonation—for that, you need dense material between you and the blast.

Radiation sickness progresses in stages, adding increasingly severe effects. RadAway provides an immediate purge and a temporary cleansing effect. Sleep, milk, and water offer smaller or situational recovery. The Geiger Counter reports ambient radiation and accumulated dose.

Recipes and Progression

The mod is designed around Create: Big Cannons and uranium processing. Dirty bombs require processed uranium materials rather than raw ore. The Radiation-Safe Canister is built from lead and steel. Fission and fusion shells require the full enrichment chain; fusion additionally requires deuterium handling. The centrifuge is intended to be the main bottleneck.
