Understanding Threat Types
Raid Types and Responses
- Tribal Raids: Large numbers, primitive weapons, vulnerable to turrets
- Pirate Raids: Mixed weapons, moderate armor, balanced threat
- Mechanoid Clusters: Heavy armor, advanced weapons, require specialized tactics
- Siege Attacks: Mortars and defensive positions, need mobile response
- Drop Pod Raids: Bypass defenses, require internal security measures
Understanding each faction's technology level and equipment is crucial for effective defense planning. Learn more about faction tech tiers and weapon capabilities to better prepare for specific threats.
Environmental Threats
- Mad Animals: Fast, numerous, weak to area damage
- Manhunter Packs: Persistent threat, require secure shelter
- Infestations: Internal threat, need prepared response teams
Defensive Structures
Wall Systems
Effective wall design principles:
- Material Choice: Granite > Limestone > Steel > Wood
- Double Walls: Increased durability and insulation
- Embrasures: Allow shooting while providing cover
- Corners and Angles: Reduce splash damage vulnerability
Proper defensive wall integration requires careful colony planning. For comprehensive base design strategies that incorporate defensive structures, see our optimal colony layout guide.
Killbox Design
The ultimate defensive structure:
- Funnel Design: Force enemies through narrow corridors
- Cover Placement: Sandbags and walls for colonist protection
- Turret Positioning: Overlapping fields of fire
- Trap Integration: Spike traps and IED placement
- Escape Routes: Multiple exits for tactical withdrawal
Effective killbox design relies on understanding how raiders pathfind and make movement decisions. Learn how to exploit AI pathfinding behavior to funnel enemies exactly where you want them.
