No self-respecting Wastelander would roam the post-apocalyptic Earth of Fallout without a Pip-Boy.

That's why ThinkGeek plans on releasing a fully functional Pip-Boy that's more than a cool prop: this Pip-Boy actually works with the help of your smartphone. But the Pip-Boy Deluxe Bluetooth Edition is much more than an oversized phone case that just happens to fit on your arm.

"With an integrated screen and its own on-board software and hardware, this Pip-Boy pairs with your Bluetooth phone or tablet to give you access to your phone's ability to take and place calls, as well as its contacts, SMS messages, and audio files," ThinkGeek writes on the product's page. "Even when not paired, the Pip-Boy: Deluxe Bluetooth Edition can still be used as an alarm clock or a cosplay prop, displaying the Status, Special, and Perks screens from the game. Oh - and did we mention that most of the knobs, dials, and buttons actually work?"

The armband for the Pip-Boy is lined with foam and should fit most arms. It's also relatively lightweight so that Wastelanders don't experience arm fatigue while out there wandering through the world.

ThinkGeek spent a lot of time and attention to detail with its Pip-Boy, too: it does double duty as a charging base and has a compartment that actually opens up to reveal a holotape (which is actually a USB drive). This Pip-Boy even features a cosplay mode that lets its wearers display the stuff fans really want to see, including screens that display status, specials and perks.

ThinkGeek's Pip-Boy will also keep you from getting lost: yes, there are maps, too.

This officially licensed Fallout 4 piece of merchandise, though, doesn't come cheap and could cost more than the smartphone that it works with. For hardcore Fallout fans, though, it's still a must-have at $350. But there's still a wait for it to actually come out (although preorders are available): this beautiful piece of post-apocalyptic tech won't arrive until November, which is good, because ThinkGeek is still working out the bugs on it.

"We're working with a prototype right now. When we get the actual product, we'll add details like screen resolution, thumb drive size, wireless range, frequency response, how long it'll stay powered on one charge and how long it takes to recharge," ThinkGeek writes. "We wanna know those things, too."

Now grab your Pip-Boy and get out there: Preston Garvey has a settlement that needs your help!
