Reactor 4: NPP Builder

Retro nuclear base-building. Make power. Hide waste. Trust the experts. They saw the explanation scene. Several times. On social media.

The mandate

More megawatts.

A small, sharp, retro industrial builder where every helpful structure creates a new administrative personality disorder.

Ancestry, regrettably documented

A touch of C&C. A small cartoon injury report.

We wanted a hint of classic Command & Conquer in the structure language: compact industrial buildings, legible base silhouettes, the pleasant feeling that someone in a sidebar is about to approve a bad idea.

Then Happy Tree Friends wandered through the safety briefing and improved morale by making it worse. Cute forest energy. Dark outcomes. Educational, depending on what you think education is.

Operational clarity

The manual is mostly alarms.

Build fast, upgrade badly, then discover that stability is not a mood. It is a number, and it has been falling while you were reading this.

Power output

Fuel rods, RBMK rooms, and forbidden spheres make MW. They also make heat, because nature enjoys footnotes.

Core stability

Coolant pumps, towers, and control rods keep the facility calm enough for the UI to remain polite.

Waste

Storage begins as planning. Then it becomes architecture. Then it becomes a character flaw.

Credits

Heat becomes invoices. Invoices become upgrades. Upgrades become why the siren has a second verse.

Manifest-approved hardware

Structures currently trusted by the game.

Cross-checked against the runtime asset manifest. No imaginary buildings. Those are for committees.

Fuel Rod Assembly

Cheap MW with a healthy respect for heat.

Coolant Pump

Earns credits while pretending the plan is sustainable.

Cooling Tower

A large vertical apology to thermodynamics.

Control Rod Cluster

Says no to neutrons. A rare public service.

Nuclear Waste Dump

The place where "later" gets a fence.

Containment Spire

Insurance likes exactly three. Very spiritual.

Turbine Hall

Turns useful heat into civilization's favorite grief: billing.

RBMK Control Room

Historic confidence, now clickable.

Plutonium Extractor

Revenue likes it. Stability has filed a complaint.

Thorium Breeder

Eats waste chunks and judges procurement in silence.

Demon Core

Large output. Catastrophic heat. Read the screwdriver policy never.

Solar Panel

Morally excellent. Operationally decorative.

Shareware spirit

Reactor 4 is free because making free things for fun remains one of the few clean technologies with decent historical evidence.

Send it to the friend who became a reactor expert after one prestige television scene and three comment threads.

Early 90s shareware understood the assignment: loud screens, strange confidence, and a blunt request to copy the thing for someone else. So yes, share it. The forest comrades believe in you. Their legal department does not.
