Side QuestsProps and objectives are live at game start. You may barter or use what you have found to gain favor with the minor factions including caps, New Vegas dollars, and information. Event-specific props given as a mission by minor factions will have SIGNIFICANTLY MORE WEIGHT in their decision to side with your faction or not. Factions will side with whichever faction has treated them the best and completed more of their side missions. It will be the minor factions CHOICE what side they chose to join at the end of the day, so treat them well.
New Vegas – Find caps stashed at bases to buy information and goodies. If a side steals from or treats this faction badly, the faction is less likely to help them. New Vegas is all about winning, and a winning side is a loyal side. The end-game alliance will be decided by New Vegas based on loyalty points.
Boomers – The Boomers are an invulnerable group of isolationists based out of Nellis Air Force Base (Bravo Base). They will meet any attack with explosives. However, if you persuade this faction to join you, they will lob explosives at your enemies. The end-game alliance will be based on quest completion and loyalty points.
BOS - The Western Chapter of the Brotherhood of Steel are located in their bunker at Hidden Valley (Gully Base). They have power-armored troopers who are invulnerable to small arms for a short time. Completing their quests will earn their cooperation for your faction.
Followers - They will wander around and have no set base. They can instantly replenish bandages for ANYONE they chose. Followers will remain neutral unless a faction treats them badly. The Followers role-players, with their advanced medical skills, can heal themselves and do not bleed out, thus, should be considered invulnerable. They may chose a side in the end game or may remain neutral.
