How to Beat Unbidden Fleets

Learn how to effectively counter and defeat the Unbidden, the Great Enigmas, and the Aberrant fleets in Stellaris with this comprehensive guide. Strategies, tips, and fleet compositions included.

Stats / Weaknesses:

• Resistances: High resistance to Energy Weapons.
• Vulnerabilities: Weak to Kinetic Weapons (e.g., Mass Drivers, Coilguns) and Explosive Weapons (e.g., Artillery, Missiles).
• Armor/Shields: Generally balanced, but focus fire is key.

Phases:

1. Arrival: The Unbidden will begin to spawn in a system on the edge of the galaxy, creating a portal.
2. Expansion: They will start to conquer systems, building structures and spreading their influence.
3. Reinforcements: The portal will continuously spawn new Unbidden fleets, requiring constant pressure.
4. Core Worlds: If left unchecked, they will push towards your core worlds and the Galactic Core.

Strategy:

• Fleet Composition: Prioritize fleets with a high concentration of kinetic and explosive weapons. Battleships with Artillery and Carriers (using strike craft) are effective. Destroyers and Cruisers can act as escorts and screen for your capital ships.
• Weapon Choice: Utilize weapons like Mass Drivers, Coilguns, Artillery, and Missiles. Avoid relying heavily on Energy Weapons like Lasers or Plasma.
• Technology: Research technologies that boost kinetic weapon damage, projectile speed, and hull/armor points.
• Fleet Size and Reinforcement: Build multiple large fleets and be prepared to reinforce them constantly. The Unbidden spawn rate can be overwhelming if you don't maintain a strong presence.
• Targeting the Portal: While fighting their fleets is necessary, the ultimate goal is to destroy the Unbidden portal to stop reinforcements. This often requires a dedicated fleet or a coordinated assault.
• Defensive Starbases: Upgrade your starbases in key systems with strong defensive platforms, focusing on kinetic and explosive weaponry to support your fleets.
• Diplomacy: If playing a multiplayer game or if other empires are strong, consider forming a defensive pact or galactic crisis-response fleet to share the burden.
• Economy: A strong economy is crucial to support the massive fleet production and upkeep required to defeat the Unbidden.
