Wall the perimeter

One fence stops most wildlife. Build it before you sprawl, not after, because retrofitting a live base is painful.

Turrets at the gaps

Place turrets where creatures path through. Cover the entries, not the whole wall, to spend ammo where it counts.

Power the guns

Turrets need power. Keep defense on the same grid you trust, or the raid lands when the guns go dark.

Protect production

If you must choose, defend smelters and constructors. Losing them stalls everything downstream of that line.

Sizing the fort

The building database lists turret and wall size. Plan coverage before the first raid reaches the pad.

Layer the defense

A wall plus a turret plus light is stronger than any one of them. Stack the systems so nothing slips through.

Layer the systems

Defense is layered, not a single wall. A fence, a turret and a light together stop more than any one of them alone on the perimeter.

Frequently asked questions

Do I need defense?

If creatures reach your lines, yes. A fenced base avoids most fights.

What defense first?

A wall around the perimeter, then turrets at the corners creatures hit most.
