G.E.C.K.，全稱是伊甸園創造器（Garden of Eden Creation Kit ）是由避難所科技公司的未來科技部門創造的一個宜居度改造的設施，其目的是為了重建被核彈衝擊後的廢土，它由斯坦尼斯勞斯·布勞恩博士，一名才華橫溢而且自負的避難所研究人員提出概念並設計完成。
其具體外觀是一個刻有G·E·C·K這四個字母的小型銀白色公文包，根據避難所公司的廣告，G·E·C·K擁有所有重建廢土用的種子，肥料和其他設備（核能發動機和複製機器以及其他的設施）after emerging from a Vault shelter. 每個避難所都分發了大約兩個G·E·C·K，除了8、13、112、111和101號避難所，8號的額外GECK被和13號的備用凈水晶元交換了（不知是某人故意還是巧合），101號避難所和112號避難所從來沒有被發放過G·E·C·K因為它們兩個都是永久封閉的實驗，從沒有打算開啟過。
G·E·C·K被設計成一個能複製能量和物質and miraculous terraforming 的機器，它的工作原理是將周圍的環境轉換為微小粒子然後根據一定的分子模式重組。當然這些都是由斯坦尼斯勞斯·布勞恩博士這個「巫師科學家」所設計完善的。
The tribals of the town of Arroyo, which was founded by the Vault Dweller, passed down stories of the "Holy GECK," which they came to believe was a sacred, magical item which can change the Wasteland into fertile land again.
Though the GECK may not have been the holy cure-all the tribal inhabitants of Arroyo believed it to be, in the right hands it was a very useful piece of pre-War technology that could help establish a viable new community in the post-nuclear wastelands. Alternately it was indeed a miraculous device, capable of terraforming the Wasteland into something far more habitable. Either way, after the destruction of the Enclave Oil Rig, the dwellers of Vault 13 rescued from the Oil Rig used it to rebuild Arroyo.
The GECK was instrumental in the creation of Vault City by the former inhabitants of Vault 8 (though whether the city's success can be attributed to the GECK alone is debatable). By combining their GECK's contents with power from Vault 8's fusion generator, the residents of Vault City were able to erect their settlement's first buildings and generate arable farmland.
When the Lone Wanderer locates their father in Stanislaus Braun's Vault 112, they learn that in order to make Project Purity work properly, they require a G.E.C.K. After James' demise, the Wanderer makes their way to Vault 87, a horrendously irradiated location, where they acquire a G.E.C.K. unit.
It seems that no other vault in the Capital Wasteland was issued a G.E.C.K, hinting that very few vaults were supplied with one, possibly due to the price of each unit. There is also no indication of any Vaults in the Mojave Wasteland having a G.E.C.K., nor is there mention of a G.E.C.K. in most vaults that have been mentioned in-game or in the Fallout Bible.
This version of the G.E.C.K. is a far more advanced piece of technology than the implied agricultural starter kit the developers of the previous games intended it to be. In this case, when included as a component within Project Purity's Purifier, the G.E.C.K. helps that other technology remove all radioactive particles from the water of the River Potomac that flows through it.
In Fallout 3, it is possible for the Lone Wanderer to reach the G.E.C.K. instead of allowing Fawkes to retrieve it, thus allowing the player to activate it. If this is done, a blue energy ball expands around the G.E.C.K., killing the player's character and, after a burst of white light, the most recent save game is loaded.
Vault 94 was issued with no weapons and an abundance of resources, and its residents were drawn from a pacifistic religious community. According to terminal entries found in Harpers Ferry written by Ella Ames and Mayor Miranda Vox, an ambassador from the vault arrived in town and told the survivors of the vault’s resources, and that they were willing to share them. Mayor Vox then sent a group, consisting of Billy, Cole, Lucas and Red to the vault. They all thought that the dwellers openness and altruism was a front, and after killing the vault leaders proceeded to massacre the rest of the vault residents. The group then found the security field around the G.E.C.K. and forced their way through it, then destroyed the device with a minigun. This caused the device to explode and blanket the area with a cloud of mutagenic gas, which came to be known as the Mire for its heavily mutated foliage.
The stories of Fallout Tactics 2 and Fallout: Brotherhood of Steel 2 were to revolve around "mutant" GECK units, which had become infected with radioactive pathogens and caused mutant plant and animal life to expand and consume huge swaths of land. While the origin of the Tactics 2 GECK is unknown, the GECK in Brotherhood of Steel 2 was found by a former Cypher called Miles Reese. In both situations, the GECKs were "terraformer" type units, like the Fallout 3 GECK.
Fallout: Brotherhood of Steel 2
Miles Reese was conducting research into the GECKs capabilities, which led him to the Nursery where he stole a prototype GECK with the hopes of terraforming the wasteland into a new, greener, and human free "Eden." The GECK, still not quite mastered by Miles, created a patchwork of lush vegetation in the areas he travelled through. Upon reaching the Gulf of Mexico, Miles toiled with the GECK for five years, greatly magnifying its effects, not concerned with the immense effects it was capable of when combined with an FEV environment. The GECK could now terraform on a dangerous scale, including within enclosed structures, and occasionally produced carnivorous plants.
 It could generate unnatural weather patterns and his experiments created jungles within deserts, and the Gulf, whose water had apparently retreated a considerable distance, re-flooded on an even larger scale. As Miles continued to tinker with the GECK its capabilities became sharpened and could focus its power into more specific tasks such as protecting Miles' base, the Corpse, with an organic shell. Armed with an extremely dangerous and refined piece of technology, or New Eden device as he referred to it, Miles continued with his ultimate goal. He went on to exploit the Jackals to his own end, all the while planning to eliminate them with biological mini-bombs which detonate at his command created by the GECK that he infected them with.
 A second GECK was found by the player character in an Austin gas station,
 which they would go on to use to overload Miles' mutant GECK causing a devastating explosion.
 It seems a combination of continual exposure, self-augmentation experiments and control over the GECK altered Miles into a being capable of symbiotic relations with the plant life it generated, vines protruded from his person and he was capable of merging with the plants themselves.

As the SDK
The Fallout 3 SDK (Software Development Kit), called "The G.E.C.K.", has been released and is up for download at the official Fallout 3 website. It is also available for Fallout: New Vegas.
- 根據Chris Taylor所說，GECK是Jason Anderson和Leonard Boyarsky為1代使用手冊設計的 - 原本沒有想要把它用在輻射2里。但是到麥高芬登場的時候，他們需要它，就用上了。
- The G.E.C.K. (or more precisely, its intended function in Fallout 3) might be a reference to the movies Star Trek: The Wrath of Khan and Star Trek: The Search for Spock, which revolve around "Project Genesis" and the Genesis Device. Like the variant of the G.E.C.K. encountered in Fallout 3, the Genesis Device is intended to be used to create life out of lifelessness (while killing every present living thing in its working radius upon activation).
- There is no clarification from Bethesda on how to reconcile the two radically different views of the G.E.C.K. The view of the GECK as a miracle device is a far cry from the view of the GECK as a pretty useful piece of pre-War agricultural technology.
- The Garden of Eden part of the name is inspired by the biblical location in which life was first created. This is most notable as the G.E.C.K acts very similar as it brings life back to the barren waste just as God brought life to the earth.
