⚔️ Siege Core: Base Invasions ⚔️
Defend your base. Survive the waves. Protect the Core.
Siege Core: Base Invasions turns your Minecraft base into the target of dangerous monster invasions, boss waves, elite enemies, traps, defense blocks, special events and long-term progression.
🏰 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.

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.
