Honeycombing: Layer walls inside walls inside walls. Each layer raiders break = more C4 spent, more time for you to defend.
Turret placement: Overlapping fields of fire, no blind spots. Mix heavy + tek turrets set to "Survivors & Tamed Creatures."
Double-wall technique: Place two walls with a small gap. Raiders blow the outer wall — inner wall is still intact.
Rathole / hidden base: Build inside terrain features (caves, underwater bubbles). Small footprint, hard to spot from air.
Vault placement: Center of base, most honeycombed area. Multiple vaults spread loot to force raiders to commit.
