Run Goodsprings Run

 is a quest in Fallout: New Vegas.

Quick Walkthrough
Joe Cobb wants you to kill Ringo and then help him kill the Goodsprings militia.

Detailed Walkthrough

 * Joe Cobb orders the player to kill Ringo, you will find Joe leaning up against a small house at the southeast edge of Goodsprings
 * Follow the marker to the gas station and kill Ringo, then return to Cobb.
 * Cobb will tell the player to get supplies from Doc Mitchell or Chet.
 * Chet can be convinced to supply the Powder Gangers with Leather Armor with a successful Speech or Barter skill of 25.
 * Doc Mitchell can be lied to, and then convinced with a Medicine skill check of 25 to provide aid for a "hurt traveler".
 * Lacking the skills, the player can always buy the supplies.
 * Head to Cobb and give him the supplies, and begin to invade. Most NPCs in Goodsprings will become hostile so stay alert. Many Powder Gangers will jump in, and help you take over.
 * Once the residents of Goodsprings are dead, the player can talk to Cobb and claim their reward.

Counter Quest
The counter variant of this quest is Ghost Town Gunfight. It will be failed if you've already started this quest.

Bugs

 * When you kill Ringo and tell Joe Cobb, he will ask you to get supplies from Chet, and Doc Mitchell. But before you get supplies you can kill Joe Cobb and fail the quest, but they will be locked in the help the Powder Gangers dialog speech, and you can get infinte experience, supplies, and powder ganger fame(from Chet).
 * Doing the above can grant the user extra free perks, before leaving the area of Good Springs. You can essentially level your self up to level 30, and get any perks after level 4 and keep them for the remainder of the game. In order for the glitch to work you have to level up before you leave the area, where it ask you to change your name, stats, before you continue. Once you change your stats, everything gets resetted back to basic, but you keep the perks you've picked before, and you get the full experience points you gathered aswell. It's almost like having a perk every level like in Fallout 3.

Behind the Scenes
The quest name may be a reference to the movie "Forrest Gump". Or, alternately, a reference to the movie "Run Lola Run".

Note
-If Joe Cobb dies during the course of the attack on Goodsprings, but the attack is successful, the quest will end once all hostile Goodsprings inhabitants have been killed and grant the XP reward to the player, but no further reward is obtainable since Cobb actually dies (instead of just being 'unconscious') and is not able to be spoken to.
