Are your bases constantly getting obliterated by tank shells, mortars, and missiles from warfare mods? Heavy Bunker Defenses is here to solve that problem.
This mod introduces "Heavy" variants of standard vanilla blocks (Cobblestone, Stone, Bricks, Dirt, Oak Planks, etc.). These blocks look identical to their vanilla counterparts but are incredibly dense, boasting extreme blast resistance and mining hardness.
🛡️ Key Features:
Extreme Blast Resistance (3000.0): Completely immune to standard TNT, Creepers, and heavy artillery from military mods.
Vanilla Aesthetics: Uses standard Minecraft textures, keeping your world looking clean while hiding an impenetrable fortress.
Server & Client Friendly: Works flawlessly in multiplayer for faction, PvP, and war servers.
⚙️ How to Craft: Crafting Heavy Blocks requires serious resources to balance their extreme durability. To craft 4 Heavy Blocks, place the following in a Crafting Table:
1x Iron Block (Center)
2x Obsidian (Top-middle and Bottom-middle)
6x Base Material (Fill the remaining slots with the material you want to reinforce, e.g., Cobblestone) (Pattern: Material / Obsidian / Material | Material / Iron Block / Material | Material / Obsidian / Material)
⛏️ Mining & Tool Requirements: Because these blocks are designed to stop tanks, they will also stop casual griefers.
Required Tool: You must use at least a Diamond or Netherite Pickaxe to mine these blocks and get the drop.
Mining Time: Breaking a single block takes roughly 30 to 40 seconds with a standard Netherite Pickaxe.
💡 Pro-Tip: We highly recommend using an Efficiency V (5) enchantment and Haste beacons if you plan on remodeling your bunker!
