Description

Mekanism Nuclear Weapons \& Explosives

Unofficial Mekanism addon adding 14 bombs. It adds Industrial Bomb, through shaped charges, incendiary, fragmentation, seismic, bunker buster, cryo and chemical gas bombs, up to nuclear, hydrogen and antimatter bombs. Bombs are built in the Warhead Assembler from parts and chemicals you make with Mekanism. In active development.

Every bomb can also be delivered by missile with my Mekanism Missiles mod.

Bombs

Conventional

  • Industrial Bomb: double the blast power of TNT, 3 second fuse, no radiation. The first bomb you can make, and the base of the Nuclear Bomb.
  • Shaped Charge: place it facing a direction and it cuts a narrow 24 block cone that way. Only what stands in the jet gets hurt, and it keeps its facing when another explosion sets it off.
  • Incendiary Bomb: small blast, then a wide field of napalm fire that burns far longer than normal fire, creeps downhill, ignores rain and melts snow and ice.
  • Fragmentation Bomb: breaks no blocks at all, shreds anything it can see out to 20 blocks. Cover protects you.
  • Seismic Charge: leaves no crater. The shockwave goes through walls and only breaks the weakest blocks.
  • Bunker Buster: tunnels along its heading before it goes off, so it explodes inside the target. Works from the missile silo too.
  • Cryo Charge: freezes water, turns lava to obsidian and puts out every fire in range, napalm included.

Chemical

  • Mustard Bomb, Phosgene Bomb, Nerve Gas Bomb: releases a gas cloud that flows through doorways, pools in cellars and low ground, and doesnt pass through walls. Breaks no blocks, kills crops. A full hazmat suit or MekaSuit keeps you safe from it.

Nuclear

  • Dirty Bomb: almost no explosion, enormous radiation, built from nuclear waste. It covers the ground up to 28 blocks around it in fallout.
  • Nuclear Bomb, Hydrogen Bomb, Antimatter Bomb: each tier has bigger explosion radius (32 / 64 / 124 by default) and releases Mekanism radiation into the area. Custom explosion so it doesnt crash the server/game, and a custom explosion cloud. They leave fallout over the crater floor and a band of ground around the crater.
  • Fallout is irradiated soil that leaks radiation and grows nothing. It settles on dirt, grass and sand, and on bare stone, deepslate, sandstone, terracotta, netherrack, end stone and the other normal ground blocks, then slowly turns back into whatever block was there before.

Big explosions keep going across unloaded chunk borders. Primed bombs flash and swell in time with their real fuse.

Warhead Assembler

A Mekanism style machine that builds every bomb. It takes power, 4 items and a chemical. Bombs cannot be crafted in a crafting table.

Chemicals

Made in normal Mekanism machines:

  • Nitrogen -> Nitric Acid -> Nitroglycerin (with Glycerol) -> Explosive Compound
  • Iron Oxide -> Thermite, Napalm
  • Thiodiglycol -> Mustard Agent -> Nerve Agent, Phosgene

Bomb Remote

  • Remote detonation

  • Control almost unlimited number of bombs at the same time

  • Set your own fuse time (0 - instant explosion, 600 seconds - maximum fuse)

  • Toggle redstone sensitivity of the linked bombs with "No RS: ON/OFF"

  • Displays world coordinates of all linked bombs

  • A remote is bound to the first player who uses it, so your bomb remote is safe from other players

  • Detonate bombs all at once or in the order you linked them

    • toggled by "Seq: ON/OFF"
    • detonations are separated by the fuse time

Ponder

With Ponder (or Create) installed, hold W over any bomb, the Warhead Assembler, a bomb part, Explosive Compound or the Bomb Remote to watch how it works:

Config

For each bomb you can set radius, damage, radiation and more. There are also settings for gas clouds, napalm, fallout (how wide the band around a nuclear crater is, its radiation and how fast it decays) and chunk loading of big explosions.

Usually (%appdata% -> .minecraft -> config -> mnweconfig.properties)

Requirements

  • Mekanism
