活力汽水股份有限公司建立於1931年，最初為藥物專利。It wasn't as popular as Nuka-Cola, however產品只在緬因州被地方市場認可。Vim was even referred to as a state tradition 並有望成為緬因州代表飲品； however, during the process of making this official, legal situations forced the company to back off its marketing.
核口可樂公司 was going to對活力汽水的併購before the war。公司為里德家族經營for years，現任執行長多由·里德面臨核子可樂的收購問題。However, with certain financial problems being caused by the company's legal issues, the CEO was being urged to sell the company. The only legal entanglement that the public was aware of consisted of a male employee of the Vim! Factory allegedly punching a female bar patron, though many witnesses denied this. Still, the local news attached to this story and forced the company to hold back on television advertisements and product release.
One successful form of marketing which continued despite these problems was 讓員工駕駛塗裝了的t51來作為宣傳的活力大使。Two sets of such armor are available: one in Vim! Paint at the Vim! Pop factory next to the terminal where the paint schemes can be downloaded, and another in Vim! Refresh Paint in a truck along the coastal road north of the National Park visitor's center.
<section begin="vim" /> A combination of pure Maine spring water and other extracts and syrups, the flagship beverage of the Vim! Pop corporation is slightly fermented, which helps to better bring out its unique and natural flavor profile.
In terms of restorative properties, basic Vim is the weakest of the four known flavors, yet still better than a bottle of regular Nuka-Cola. It restores 50% more health with the added benefits of being craftable and not subjecting the consumer to any additional radiation poisoning, thus making it useful especially during the early game stages. However, its usefulness is somewhat mitigated by only being available on the Island.<section end="vim" />
Provided the recipe has previously been downloaded from the research terminal inside the laboratory on the roof of the Vim! Pop factory, Vim can be crafted from the following ingredients at any cooking station:
Purified water (1)
- Fourteen Vim bottles can be found throughout the Vim! Pop factory.
- One can be found in the small warehouse in front of Eagle's Cove tannery along with various empty bottles.
- Three can be found in Beaver Creek Lanes.
- Three can be found in the Vim truck trailer south of the basement armory.
- Crafted at any cooking station.
- All flavors of Vim can be turned into their ice cold variants by putting them in Buddy and waiting at least 12 in-game hours, despite not being beers.
- No type of Vim confers any radiation to the consumer despite having been exposed to the Island's heavily irradiated environment for more than two centuries.
活力汽水, as well as its logo design, 背後的原型也叫活力(Moxie)，緬因州的官方碳酸飲料。Moxie進入美國人民的英語詞典，意為精力，勇氣，與vim是近義 (e.g. 'Vim and Vigor') based on the advertising for the soft drink in the 1930s. 與活力汽水一樣，Moxie最初的定位也近似保健產品。
