☢ HBM: Hamster Reloaded
Server Coming Soon!
Hbm's Nuclear Tech — Hamster Reloaded (HBM:HR)
Engineering, industry, nuclear power and catastrophic consequences.
Minecraft 1.12.2 — Forge
Welcome to HBM: Hamster Reloaded!
HBM: Hamster Reloaded is a community-led continuation of the classic Hbm's Nuclear Tech Mod, developed by Hamster Systems.
Build vast industrial facilities, experiment with radioactive materials, develop sophisticated weapons, launch missiles and harness nuclear energy. From complex processing chains to colossal reactors, every advancement brings new opportunities—and new dangers.
☢ What Can You Do in HBM?
The HBM experience includes:
- Nuclear reactors and power systems — Construct complex facilities and manage the risks of nuclear energy.
- Missiles, bombs and weapons — Develop advanced weaponry, from conventional equipment to devastating nuclear technology.
- Industrial machinery — Refine materials, automate production and build enormous manufacturing systems.
- Radiation and environmental hazards — Handle dangerous substances and deal with the consequences of contamination.
- Science and resource processing — Work through extensive crafting and production chains to reach increasingly powerful technologies.
- Multiplayer chaos — Team up to build a facility—or test your defences against your friends.
Warning: A badly managed reactor can turn your carefully built base into a very expensive crater.
Feature availability varies by Minecraft version and release. The list above describes the wider HBM experience, not a promise that every feature is already playable in 1.21.1.
