☢️ HBM Nuclear Tech — (OpenWar changes)
HBM brings the nuclear stuff, the explosives, some resources and heavy weapons. This page sums up what changes on OpenWar on the gameplay side (not the whole mod).
💥 Many extreme HBM weapons (missiles, warheads, nukes…) are banned on the server → see Banned items. The loot from crates and boxes is largely made up of HBM resources.
💣 Nukes far better absorbed
This is the big change. On OpenWar, a nuclear explosion doesn't flatten everything in a sphere like in vanilla HBM:
- Solid and reinforced blocks absorb a huge amount of damage: a well-built bunker can survive a strike.
- The system accounts for the solidity / structure of the walls: layers of resistant blocks stop the blast (tested example: 7 layers of CMB brick stop a "Little Boy").
- Small nukes are heavily nerfed; you need heavy firepower to punch through a real defense.
🛡️ Gameplay consequence: building thick and reinforced actually means something. A well-built base resists nuclear raids.
🧱 Rebalanced defense blocks
- The resistances of defense blocks (concrete, compound brick, ducrete, CMB brick…) have been readjusted for a coherent raid/defense balance.
- Defensive blocks are anti-piston: they can no longer be pushed with pistons (no more bypassing defenses with a piston).
🎯 Explosives are governed by OpenWar
This is the big link with the server: you don't trigger an HBM explosive freely, it's wired into the factions' war system.
| Rule | What it means |
|---|---|
| 💥 Raid Points cost | Detonating a bomb, launching a missile, throwing an offensive grenade or firing a destructive shell consumes Raid Points from your faction (cost depends on the explosive) |
| 🧑🤝🧑 Faction required | Without a faction, no detonation of an offensive explosive |
| ☢️ Nukes → faction level 20 | Nuclear weapons require the Nukes perk (faction level 20) |
| 🚫 Redstone disabled | You can no longer trigger a bomb via redstone/lever — it takes a player (who pays the RP). No more automatic nuke traps |
| 🏠 Spawn protection | No explosion can touch the spawn area ("TOO CLOSE TO SPAWN") |
| 🏭 Production locked | Machines (assembler, factory) won't build an item above your level |
| 🆓 Non-destructive shells | Shots that don't break blocks (gas, smoke, cargo) are free |
🛡️ Result: nuclear war is a resource you earn, not a spammable button.
⛽ Fuels for vehicles
HBM provides the Kerosene and Diesel fluids (and the canisters to carry them) that are used to refuel McHeli vehicles.
✅ Page verified by scanning the code (
com.hbm.openwarintegration + markers): the Raid Points / nukes / anti-redstone / spawn-protection system was added here.
