《辐射：新维加斯》并非《辐射3》的直系续作，却与原来黑岛取消的未完成版辐射3，开发代号范布伦有关。其游戏体验虽与《辐射3》相似，但故事背景设定在该作的三年之后。由於前作故事是發生在美國東岸,而本作則發生在西岸,所以前作的角色均未在本作登场。但是《辐射2》Marcus 和 Doctor Henry在本作以NPC形式出场.遊戲的最終版(內含所有擴充包)將於2012年2月7日於北美發行，2月10日於歐洲發行。
- 《Dead Money》 XBox360 : 2010年12月21日 PS3、PC : 2011年2月22日
亡者財富:講述一間休閑賭場在二百年前因核戰而從未開過,幾年後被某方紅色毒雲包圍整個鎮,在城內的人無法離開或進入而包受紅色毒雲的痛若,為了打開賭場之門,"你"要與其他三人合力打開對着賭場方向的閘門,其他三人有兄弟會的女暗殺者,FEV加人格分裂的變種人和休閑賭場的幸存者(歌手),而你面對的是兄弟會的科技狂長老Elijah.以下是由Fallout維基找的: "Dead Money is set in the Sierra Madre, an opulent and extravagant resort that was to be the greatest casino in the west, except that it never opened. The bombs fell before the grand opening, and the Sierra Madre froze in time, its state of the art security system locking the place up tight. Nothing could get in, and none of the guests could escape. The security holograms then activated and the once glorious event turned into a slaughter. After many years, the climate control and air conditioning systems within the facility began to spit strange toxins into the surrounding city, causing a red cloud to form over the area - which proved lethal to anyone who tried to explore the city. Only a mysterious group called the ghost people survived to call the city home, trapped inside what appear to be Hazmat suits, they wander the streets never speaking to their victims, only capturing them alive and dragging them away to the depths of the city deep within the Cloud.
And so the Sierra Madre faded from memory, only occasionally being seen in posters across the wastes, until it took on mythic ghost story status, a supposed "City of Gold" in the Wasteland where all the treasures of the Old World were rumored to be held. It was kept alive as a late-night saloon story by prospectors who'd claimed to have found maps leading there and were willing to part with the map for a few caps. Or a drink. Or a warm place to sleep.
The Sierra Madre is a mythical place in the wastes, with travelers risking their lives to find it. Only one man truly "found" it and lived. After the fall of HELIOS One, Father Elijah of the Mojave Brotherhood of Steel set out to find new weapons to eradicate the NCR, and in the process he found the Sierra Madre."
- 《Honest Hearts》 XBox360、PC : 2011年5月17日 PS3 : 2011年6月2日
講述白腿族與新迦南族和一位被燒去面部的人之間的故事,以下是由Fallout維基找的: After the First Battle of Hoover Dam, Caesar sent Ulysses to the Great Salt Lake to rally the White Legs to destroy New Canaan. With his help, the White Legs found a large supply of weapons. The White Legs then destroyed New Canaan, sending Joshua Graham (also known as "The Burned Man"), and the New Canaanites to Zion Canyon, where the Dead Horses stand with them against Caesar. The Courier then arrives in the Zion Canyon and meets the Burned Man, Joshua Graham, who is surprised that it is a different Courier than Ulysses that came to him, as he had figured Ulysses would come to murder him. This sparks the beginning of Honest Hearts.
Honest Hearts takes you on an expedition to the unspoiled wilderness of Utah’s Zion National Park. Things go horribly wrong when your caravan is ambushed by a White Legs raiding band. As you try to find a way back to the Mojave. The Courier becomes embroiled in a war between tribes and a conflict between a New Canaanite missionary and the mysterious Burned Man. The decisions the player character makes will determine the fate of Zion.
- 《Old World Blues》 2011年7月19日
講述一個科技先進的地方名為Big MT的故事,以下是由Fallout維基找的: "The residents of the Mojave have long assumed the trackless wastes of the ‘Big Mountain' are a no-mans' land, a desolate stretch where no living thing can survive. In Old World Blues, you discover that it is anything but..."
In Old World Blues, the Courier discovers how some of the Mojave’s mutated monsters (cazadores and night stalkers) came into being while unwittingly becoming a lab rat in a science experiment gone awry. The Courier must scour the pre-War research centers of Big Mountain in search of technology that can either turn the tables on their kidnappers or help them fight against an even greater threat.
After being transported to the Big MT research crater, you find that you're the only hope of saving the "Think Tank" – a strange group of post-human researchers who inhabit the facility. They enlist your aid to save them from their own experiments - experiments that have gone horribly out of control and an evil scientist who threatens their lives. As you explore the Big Mountain crater and its many underground labs, you’ll confront strange mutated animals, battle terrifying new atomic robots and discover a new home base to call your own. Recover all the weapons, armor and tech of the pre-War era and use them to help save all of Science and hunt down your own brain, spine and heart which have been removed from your character in an experiment.
- 《Lonesome Roads》 2011年9月20日
以下是由Fallout維基找的: Lonesome Road brings the Courier's story full circle when you are contacted by the original "Courier Six", a man by the name of Ulysses, a former Frumentarius of Caesar who refused to deliver the Platinum chip at the start of the main storyline in Fallout: New Vegas. In his transmission, Ulysses promises the answer as to why, but only if you take one last job - a job that leads you into the depths of the Divide, a landscape torn apart by frequent earthquakes and violent storms. This is the fabled location of the battle between the Courier and Ulysses. The road to the Divide is a long and treacherous one, and of the few brave enough to walk it, none have ever returned.
