For strategies on building defenses, see Defense structures.

Colonists can build the following security structures to help protect the colony from harm:

Sandbags	Barricades	Mortar	Spike trap	Mini-turret	Uranium slug turret	Autocannon turret	Foam turret
Rocketswarm launcher	IED trap	IED incendiary trap	IED EMP trap	IED firefoam trap	IED smoke trap	IED antigrain warhead trap	IED tox trap

Security constructions

A security construction is a building your colonists can build that helps protect your colony.

Types of security structures:

• Cover - Barricades and sandbags both provide good cover, excellent for defensive firing positions. Largely interchangable except for crafting recipes, with barricades using wood, stone and metals and sandbags using textiles. See below for summary, or either barricades or sandbags for material comparisons.
• Turrets - Several types of totally autonomous weapons with different optimum ranges. Best when placed to cover common entry points, but requires power and occasional rearming.
• Mortar - Long-range and very damaging manned turret but requires ammunition and replacement barrels, have long warmup and cooldown times, and are highly inaccurate. Also has a variety of ammunition types for different effects. See mortar for details.
• Traps - Single use, passive structures that inflict a one-time injury. Colonists and friendlies will try to avoid them, and some enemies are smart enough to avoid them. Friendlies have a 0.4% chance of triggering traps. They are categorized into two types:
  • Spike trap - a simple single-target damage source. See spike trap for material comparisons.
  • IEDs - made from mortar shells, they explode in a radius for an effect dependent on their type. See below for summary.

Cover

Note that these values are the base values - all stats will be affected by material choices. See either barricades or sandbags for material comparisons.

Name	HP base	Cover	Beauty	Work to Make	Flammable	Material Cost
Barricade	300	55%	-3	320	100% Material dependent	5
Sandbags	300	55%	-10	180	0%	5

Traps

Spike traps deal 100 Sharp damage to a single, modified by the material's Melee Sharp Damage multiplier. See spike trap for material comparisons.

Name	Damage	Type	Radius	Notes
IED trap	50	Bomb	4	-
IED incendiary trap	10	Flame	4	Ignites pawns and surroundings causing further damage
IED EMP trap	50	EMP	11	Does no actual HP damage, stuns mechanoids and some structures
IED firefoam trap	-	Firefoam	10	Does no damage, puts out and prevents fires
IED smoke trap	-	Smoke	8.6	Does no damage, only deploys smoke.
IED antigrain warhead trap	550	BombSuper	15	Antigrain warheads are not craftable
