Westside is a part of New Vegas, just as much as it's a part of the Wasteland. In the end, stranger, we need them both to continue making our fate.
The Westside is a district of New Vegas, located west of the New Vegas Strip. Though it is one of the poorer residential areas of the city, it houses its own militia and considers themselves apart from the city. Westside became more or less self-sufficient, growing its own food and maintaining its own water supply.
The residents often complain of problems with the Fiends, who often harass and even kill them in constant raids. A smaller gang, the Scorpions, also has a presence around the southern outskirts.
While it appears poor and run down at first glance, the community produces enough food, clothes, weapons and medicine to encourage trade. The locals prize their independence and work hard for the common good. The Westside Co-op formed to better organize their work, eventually creating enough food to both meet the needs of the community and trade with the outside.
The residents of the fortified Westside Zone have a small, but tight-knit community based around growing crops for themselves, and to sell to travelers and larger factions. Currently embroiled in tense negotiations with the NCR regarding the siphoning of their water supplies, the Westside Co-op features a motley band of folk, including an escapee from New Reno named Clayton Etienne, and a Follower of the Apocalypse called Tom Anderson, who is single-minded in his defense of this operation.
The larger part of the neighborhood, exposed to the Mojave Wasteland, is surrounded by a small network of walls, while the residential and commercial area is walled completely, except for two gates. The Westside's services include a food store, a brothel, a liquor store, a pawn shop, and a fighting arena where matches can both be fought and bet upon.
All non-unique Westside residents (i.e. Westside Militias and Westside residents) will respawn after 3 days if killed. Westside Militia at the perimeter of the community will periodically get into firefights with randomly spawned Fiends.
The truck just along from Miguel's Pawn Shop explodes spectacularly if shot in the hood, injuring any passer-by but is otherwise ignored and doesn't have a negative effect on the player's status.
