Object description

Land mines are small defensive emplacements that explode in proximity to enemies. They leave behind ghosts that can be automatically rebuilt with construction robots.

Mechanics

Placement

Land mines can be placed on both natural and artificial tiles like concrete, and do not obstruct players, vehicles, nor projectiles.

They can be placed freely and do not snap to the tile grid, but grid alignment is possible with blueprints, like the one below.

Arming

When placed, land mines start inert and spend 2 seconds arming and burying themselves in the ground. They can be targeted by enemies during this time, and as military structures, they are attacked on sight.

Once armed, land mines become untargetable and enemies ignore them. However, mines can still be destroyed through indirect fire from area of effect attacks, like a spitter's acid projectile.

Trigger and explosion

Land mines have a 2.5 tile trigger radius and 6 tile damage radius. They deal 250 explosive damage and stun any survivors for 3 seconds. They do not damage allied buildings, vehicles, or players.

Enemies do not aggro when damaged by land mines, making land mines the only passive defense in Factorio. However, this can be difficult to utilize since enemies do aggro when they see a newly-placed mine, as noted above.

Destruction

Armed land mines detonate if they are destroyed by damage (rather than triggered), while unarmed land mines do not.

Like most structures, land mines are vulnerable to friendly fire from area of effect weapons, like grenades, flamethrower turrets, rocket turrets, and railgun turrets.

Land mines can be deconstructed as normal.

Control behaviors

	This article contains content on features that will be included in a future update.
	These features are confirmed, but not yet added to the game.

Land mines can be connected to circuit and logistic networks.

• Enable if: Triggers detonation. Using this control behavior disables proximity-based triggering.
