Realistic Nukes Mod brings physically accurate explosions into your game. It scales craters and damage perfectly so one block equals one meter in real life. You can drop bombs ranging from a small blast to a massive 2.5-megaton event that wipes out entire biomes and leaves craters that reach all the way down to bedrock.

Features:
- True-to-Scale Physics: Calculates craters, blast waves, and heat damage using real-world math where one block equals one meter.
- B83 Assembly: Lets you build a custom bomb piece by piece on a bracket, changing its power from 1 kiloton up to 1.2 megatons.
- F485 Warhead: Adds a massive 2.5-megaton bomb that you place down and detonate for maximum destruction.
- Destroys different blocks at different distances, wiping out stone near the center while only breaking glass and leaves further away.
- Starts fires and burns trees down to the trunk if they sit inside the heat flash zone.
- Burns mobs that stand out in the open, but keeps them safe if they hide behind solid cover.
- Fills the crater with water to create a giant lake if the bomb goes off near an ocean or river.
- Generates different crater shapes depending on where the bomb explodes, like underwater, underground, or high in the air.
- Spreads the block breaking over time so your game stays stable even during the biggest explosions.
- Updates untouched chunks with damage as soon as you walk near them after a large blast.
How to Use:
- Place the B83 Assembly Bracket in a clear 1×2 space on the ground.
- Right-click the bracket with the Plutonium Primary, then the Electronics, Tritium Reservoir, Interstage Front, and finally the Canned Secondary Assembly.
- Sneak and right-click with an empty hand while building to change the power level.
- Right-click the finished bomb with an empty hand to close the casing and take it off the bracket.
- Sneak and right-click the bomb with a Radio Detonator to link it, then right-click anywhere to fire it.
