Traps in Fallout 4 can be found all over the Commonwealth.

Types of trapsEdit

Randomly around the Commonwealth there will be land mines on the ground and sometimes hanging from chains. These will explode when touched.


Vehicles sometimes explode due to gunfire bouncing off of them, grenades or other explosions, or melee weapons.They can pose a serious threat to the Sole Survivor if not careful, but generally will not kill the player.

Natural trapsEdit

Traps formed naturally from both flora and fauna, generally emitting radioactive clouds.



The barnacle, a crustacean, is an unusually large barnacle found in coastal regions generally clinging to rocks and other vertical surfaces next to the sea.

For example at Neponset Park, Nahant Oceanological Society and an unmarked location NW of Breakheart Banks. Upon approaching it, the barnacle releases a radioactive cloud that irradiates the Sole Survivor at a rate of +30 rads/s for a few seconds.

Irradiated thistleEdit

Fo4-Irradiated Thistle

A spiky leafed, purple coloured plant growing in open grassland and around shrubs. Typically it will release a visible, green tinged radioactive cloud producing 30 Rads/s when the player character moves close to the plant. They tend to grow in groups which can increase the potential dosage.

A group of two specimens can be seen growing next to the wooden electricity pole just west of the Red Rocket truck stop near Sanctuary. A larger group of five-six grow a little way north of USAF Satellite Station Olivia in a dry clay patch by a wooden basket.

Man-made trapsEdit

Makeshift bombEdit


The makeshift bomb can be found in various places such as Hugo's Hole and has the appearance of a cigar box with a small circuit board with some diodes in it and duct tape holding it to a wall . Upon disarming a makeshift bomb, the player receives a spring, steel & copper.

Jury rigged gunsEdit

There are numerous types of guns jury rigged to fire at an entrance way when triggered. These include double-barrel shotguns, pipe pistols, laser rifles and missile launchers. These are usually very weak and, furthermore, normally miss their targets.

Gas trapEdit

Rooms which are filled with a flammable gas, causing a wavy effect in the air. Firing a weapon inside the gas cloud ignites it. One can be found in the diner in Easy City Downs. Another can be found in a shed at Saugus Ironworks.

Gasoline trapEdit

Rainbow colored discoloration on the ground indicates gasoline. Firing a weapon at the fuel ignites it. Gasoline can be found in the Hopesmarch Pentecostal Church, and the basement of the Shamrock Taphouse.

Flamethrower trapEdit

A flamethrower jury rigged to shoot fire at the player. Typically activated by opening the door they are found behind. This trap can be crafted at player-owned settlements.

Grenade bouquetEdit

Fo4 frag grenade bouquet

The grenade bouquet is one to three frag grenades being held by a small wire or string that, upon triggering, pulls the pin and drops them to the ground. Upon disarming a bouquet the player receives a number of grenades corresponding to how many were in the bouquet.

Radiation trapEdit

Often set by Children of Atom, these small devices emit radiation when triggered by tripwires. They act much like barnacles when they release a small cloud of radiation, but unlike barnacles, can be ignored or even skipped with high enough of a sneak skill.

Weak plankEdit

Fo4-Weak Plank Trap

Typically one or two wooden planks forming part of a makeshift bridge will give way as the player character moves over them, potentially causing them to fall and possibly take fall damage. These planks can sometimes be identified by a shallow v-notch carved or worn into the boards near the middle.

An example of this type of trap can be found on the south elevation of Saugus Ironworks where a small plank bridge joins two sections of steel stairway. The outer two planks will creak then break away when walking or running across.

Tesla trapEdit

This trap is generally located on the ceiling inside buildings, and looks like a large metal smoke alarm with electrodes protruding from its sides. Activation from a pressure plate or trip wire causes the trap to emit lightning bolts in random directions that will cause energy damage. This occurs for a short period of time, after which the trap goes inactive and will not trigger again unless the location it is in is reset. This trap can be crafted at player-owned settlements.

Noise making trapsEdit


Spotlights are lights which scan across an area and can detect intruders, alerting nearby enemies by beeping loudly. They will continue to follow intruders with their light as long as they are in the light's line of sight.

Clapping cymbal monkeyEdit

Cymbal monkey

These monkey dolls will raise their head to look at nearby intruders with green eyes. Should the intruder remain in their line of sight too long, their eyes will begin flashing red, and they will begin clapping their cymbals together. This will alert nearby enemies to the intruder.

They may also be rigged to trigger nearby traps; this is indicated by a spinning antenna behind its shoulder. The cymbal monkey can be quietly disarmed by shooting off its head with a silenced weapon.

Tin can chimesEdit

A string of tin cans suspended from a doorway or ceiling. They will chime upon contact and alert nearby enemies to one's presence if the Sole Survivor or a companion runs into them. Collecting them will also cause the chimes to sound.

Firing mechanisms and initiating actionsEdit

Handmade trip wireEdit


The handmade trip wire appears to be a green thread or fishing line that's put across walkways to make a trap go off. Upon disarming the tripe wires the Sole Survivor is awarded a gear and a spring

Laser tripwireEdit

The laser tripwire is a fairly obvious tripwire as it emits multiple red lights that are easily seen.

Tension triggerEdit

Fo4 tension trigger

The tension trigger appears to be a small box with short range radio capabilities as it has antennae and no physical connection with what they activate. They are triggered by opening the door or container they are attached to.

Bathroom scaleEdit


The bathroom scale appears to be a normal bathroom scale with the word "Dead" written on the numbers. They tend to trigger nearby traps, and are sometimes rigged as landmines.

Wasteland WorkshopEdit


Certain mine traps have been configured by the game designers to change positions or disappear completely upon a reload of the same cell, possibly to reduce the reward for an instant reload. For example, you may enter an area and fail to spot a mine which explodes and damages you. You decide to do a quick reload and walk through the same area now that you know where the mine is, so you can disarm it and gain the mine as loot. Upon reloading you may find the mine is not where it was before, either appearing in a different place or simply gone from the area.
