Heavy Bunker
by Yoplay
Heavy Bunker is a Forge decoration mod that adds reinforced versions of common vanilla blocks, built to resist explosions and heavy weapons.
What it does
Each heavy block copies the look of its vanilla counterpart, such as cobblestone, stone bricks, dirt or oak planks, so a fortified base can keep the standard Minecraft appearance. The blocks are described as extremely dense, with a listed blast resistance of 3000.0, and are said to be immune to standard TNT, creepers and artillery from military mods. The mod was made for bases that are often destroyed by projectiles from warfare mods.
Heavy blocks are crafted at a crafting table using four heavy blocks as the result, with two obsidian blocks in the top-middle and bottom-middle slots and a base material in the remaining six slots. Breaking one requires at least a diamond or netherite pickaxe, and with a netherite pickaxe the author estimates each block takes about half a minute, so Efficiency V and haste from beacons are suggested for remodeling. Heavy Bunker runs on client and server and is published for Forge only, with the latest file 3.0 for 1.20.1, released on 2026-07-12. It is not open source and is released under All rights reserved.
