The Pip-Boy 3000 Mark IV is a multi-functional device that features a built-in Geiger counter and has been programmed to display the wearer's stats, area maps, inventory, and item properties. Its screen also acts as a flashlight in low visibility areas and it has a dial for tuning into radio frequencies. It is a more ergonomically designed and up-to-date version of the Pip-Boy 3000 used in other vaults.
Pip-OS supports user health notifications, munitions monitoring, quest tracking, and audio playback. Additionally, it integrates with the onboard computers of power armor, allowing a user to access their Pip-Boy from within the armor via a HUD-like on-visor display. The statistics menu, or 'Stats', shows the user's damage and resistance, health, AP, experience, and limb condition. The levels of their SPECIAL attributes are shown in a separate tab, with a third tab displaying various perks they have acquired.
The inventory menu is a system used for viewing and managing collected items. The menu also displays total caps and carry weight at the bottom of the screen. It is sorted into seven tabs:
- Weapons: All weapons, grenades, and mines fall in this tab. Specs of weapons can be viewed and compared, as well as equipped and unequipped. An icon on the bottom of the screen displays the current damage output.
- Apparel: All armor and clothing appear in this tab. Specs of armor and clothing can be viewed and compared, as well as equipped and unequipped. The bottom right corner of this screen displays all current resistances.
- Aid: Medicines, chems, food, and drinks are sorted here and can be used and consumed in this tab. The health bar is also shown at the bottom of this screen.
- Misc: Miscellaneous items such as keys, holotapes, notes, bobby pins and items which fall under no other category are in this tab. Holotapes and notes can be played or read here.
- Junk: Resources for crafting, items that can be scrapped for resources and resource shipments are listed in this tab.
- Mods: A tab for weapon and armor modifications used at weapon and armor workbenches.
- Ammo: Lists all types of ammunition for guns currently in inventory.
It should be noted that this Pip-Boy while being an upgraded version of the Pip-Boy 3000, does not have the same keychain functionality and is susceptible to key clutter in the miscellaneous tab.
The data menu is mainly used as a means to keep track of overall progression, as well as view the current date and time in-game. It is divided into three categories:
- Quests: All current and completed quests and miscellaneous objectives can be seen here.
- Workshops: This tab keeps track of statistics for any settlement currently under control, such as current population, food and water production, defense, the number of beds and total settlement happiness.
- Stats: This function lists a variety of trivial in-game statistics that can be viewed. It is divided into five subcategories:
- General: Displays general statistics, such as the number of locations discovered and cleared, days passed, hours slept, etc.
- Quest: Lists the number of quests that have been completed and what kind.
- Combat: Displays combat statistics, such as the numbers and types of enemies killed, critical strikes used and several perk-related accomplishments.
- Crafting: Shows the number of things that have been crafted, plants harvested, settlements unlocked, items scrapped, objects built and supply lines created.
- Crime: Lists the number of crimes that have been committed, such as murder and the number of locks picked and computers hacked.
The map menu opens centered on the device's current location. It can switch between the world and local maps and can be used to view current supply lines between settlements. The user can view all discovered and marked locations set waypoints and find the location of a current quest objective.
No longer in the data menu, radio stations now have their own tab. Diamond City Radio and the Classical Radio will always be shown by default, with new radio frequencies appearing as they are found. If outside the broadcast range of a frequency, it will be grayed out and will not be selectable.
The Pip-Boy display can be set to an over-bright mode to provide illumination in dark areas. The color of this light matches the user's selected display color preference, which is changed in the actual game display options. To activate the Pip-Boy light, hold down the button used to access the Pip-Boy.
A unique feature of the Pip-Boy 3000 Mark IV is an adapter plug attached to the underside of the device. This plug is used to perform diagnostics on power armor, as well as open and close the main doors of vaults in the Commonwealth, effectively making the Pip-Boy a vault key. In addition, the plug is also used to gain control of robots if the Robotics Expert perk is active.
- Minigames can be played on this model of the Pip-Boy, using holotapes found by the Sole Survivor.
- The Sole Survivor finds their Pip-Boy instead of being issued one by Vault-Tec. The Sole Survivor is required to pick it up and attach a cable to interact with the main door in order to leave.
- If the Pip-Boy light is turned on in the PS4 version, the Dualshock 4 controller's light bar will turn green to match the default color of the Pip-Boy light. When turned off, it will revert to its previous color. If the player dies or loads another save file while the Pip-Boy light is on, however, the light bar will remain green until the Pip-Boy light is turned on and off again.
- If left idle while looking at the Pip-Boy for an extended period of time (usually around 2 minutes), the Sole Survivor will occasionally tap on it, hit it to fix bugs, briefly place it down to look in front of them, or look at its underside.
- With the installment of Vault-Tec Workshop, Pip-Boys can be given to settlers and companions (excluding Strong, Ada, Dogmeat, and Codsworth). Upon giving a companion a Pip-Boy, they will automatically equip it, and the only way to remove it is through console commands. The change is only cosmetic.
- The Pip-Boy can be modded at an armor workbench; however, only the "Standard" variant is available, without Creation Club content installed.
- If an apparel item that has a flashlight modification installed is equipped, the flashlight mod will replace the Pip-Boy's light. One example is the mining helmet.
Behind the scenes
- The Pip-Boy 3000 Mark IV was first revealed on June 3, 2015, in the Fallout 4 announcement trailer.
- A real-world model of this Pip-Boy 3000 Mark IV was marketed as a promotional item by Bethesda. It can hold smartphones of certain sizes inside and has an app to be used with it. The app is a full version of the Pip-boy and can be used to interact with the game instead of using the Pip-Boy in game. The app will update the current quest, inventory, stats, etc. of whatever game it is synced to. It is included in Fallout 4 's Pip-Boy Edition with a display stand.
- On November 11, 2016, the Pip-Boy deluxe bluetooth edition was released. This model has a built-in screen, functioning knobs, and an opening holotape player, but does not interface with the game.The display stand doubles as a speaker and a charging station.
- On occasion, the Pip-Boy will not show up when accessed. This can be fixed by saving and reloading the game. This can also be fixed by pressing the escape key twice.[verified]
Occasionally after using "shift-tab" to access the Steam overlay, the Pip-Boy might not pull up again. [verified]
- To fix this, simply reopen the overlay and close it again.
- When viewing the map, the cursor can not be moved, zooming in and out still works.[verified]
- When in chameleon armor while invisible, the Pip-Boy menu will not show up the first time. This can be fixed by exiting and re-entering the menu. Also standing up after and entering the Pip-Boy and entering the menu will have the screen still in chameleon effect and have the screen translucent while still having the border.[verified]
- When changing tabs from either STAT or INV to MAP, the knob indicating the currently displayed tab will bug and not move to MAP until the player goes to DATA or RADIO.[verified]
- add-on Vault-Tec Workshop, the Pip-Boy will appear in the workbench menu but when selected, cannot be modified in any way.[verified] If using an armor workbench with the
