Third Street Saints

The Third Street Saints were originally a street gang that eventually gained powerful corporate backing from the Ultor corporation and considerable brand recognition across the country. They were made famous in Volition Inc.'s Saints Row game series, and make an appearance in Cobalt Flats near the end of the game.

Role in Cobalt Flats
The Saints don't appear in the game until the last few storyline missions. After Luciana's actions begin to gain notoriety, the leader of the Saints sends Malcolm Bright, along with a group of Saints members, to Sharpton to offer Luciana membership in the Saints in exchange for allowing their organization to operate within the city's limits.

If Luciana agrees, she becomes a member of the Third Street Saints and must then, along with Saints backing, push the other competing factions out of Sharpton once and for all, establishing the Saints as the rulers of the city, with Luciana as the chapter's leader.

If Luciana chooses to side with someone else, she will be required to fight the Saints and force them, along with the other factions she sided against, out of Sharpton.

Trivia

 * If she sides with the Saints, Luciana will point out that she prefers the color green as a gang color to that of purple. This is an inside joke aimed at the fact that green was originally chosen as the color for the Third Street Saints, but later changed to purple due to a conflict with the main gang color in GTA: San Andreas.


 * After completing Hostile Takeover and the following endgame missions, if Luciana sided with the Saints, the Golden Tower's searchlights will change from white to purple and the large gold bar emblem on the front of the building will be replaced with a silver Fleur De Lis. The Saints are the only faction where choosing them changes anything about Luciana's headquarters.


 * If the player chooses to side with the Saints and chose to employ Matt Miller during the Hacky Sack mission, he will state that he no longer feels comfortable working alongside Luciana now that she is involved with the Saints due to "past creative differences." This is a direct reference to the fact that Matt was actually a main antagonist in Saints Row: The Third, and is likely still in hiding from them.
