🏰 What is Siege Core?

Siege Core: Base Invasions adds a full base-defense system to Minecraft. Craft and place a powerful Siege Core, build defenses around it, invite your team and prepare for enemy waves.

Your base generates Threat Points. Once the threat level is full, an invasion is prepared. Enemies will attack your base and try to destroy your Siege Core.

Survive all waves to progress.
If the Core falls, the invasion is lost.

🛡️ Defense Blocks

🪵 Siege Barricade

A defensive blockade used to slow down enemies, create chokepoints and protect the Core. Siege mobs can attack barricades, giving players time to react.

🩸 Spike Trap

Damages Siege mobs that step on or move across it.

🐌 Slow Trap

Slows Siege mobs and helps control enemy movement.

🔥 Flame Trap

Deals area damage to Siege mobs and is useful against groups.

❄️ Frost Totem

Slows nearby Siege mobs in a radius.

💚 Repair Pylon

Supports your defense by helping repair the Core during active invasions.

⚠️ Threat System

Your base builds up Threat through time, activity, monster kills and ore mining.

Default invasion threshold: 3500 Threat Points

🌊 Stages, Waves & Wave Preview

The HUD and Core UI can show Wave Preview information such as enemy count, boss wave status, event chance and possible Infinity Mode combinations.

📈 Core Level / Base Level

Completing waves and invasions grants Core XP. Higher Core Levels improve long-term base strength, durability and reward scaling.

💬 Why Siege Core?

Siege Core is designed to make Minecraft bases matter again. Instead of building a perfectly safe home, your base becomes something you must actively defend.

Build. Defend. Survive. Upgrade. Repeat.
