After Act II

In this chapterYes Man, Benny's Securitron, offers the Courier an independent path in which no faction controls the Mojave.

The independent path begins with Yes Man, a cheerful and servile Securitron. He explains that the Courier can control New Vegas without serving any faction, if they can remove House and gain control of the Securitrons. The Courier must visit the Fort, win over the Securitron army and prepare for a battle against all sides. Yes Man provides information and tools, but the Courier must do the work.

The Wild Card path appeals to players who distrust all factions. It offers freedom, but it requires diplomacy and force. The Courier cannot hide behind a banner; they must persuade or defeat everyone.

Yes Man's personality adds humour to a heavy storyline. He is an AI who agrees with everything, and his lack of moral guidance leaves the Courier as the only real decision-maker. It is a statement about the burden of choice. The independent ending is the riskiest. New Vegas has no ally and no guarantee of survival, but it has autonomy. The epilogue leaves the question open.

In this chapterAt Hoover Dam General Oliver greets the Courier, the Legion attacks through the intake tunnels and the Boomers, the Khans, the Brotherhood and the Enclave Remnants appear as allies.

The battle brings all of the Courier's choices to a head. The NCR defends the Dam, the Legion attacks through the intake tunnels, and allied factions arrive depending on earlier quests. The Boomers conduct bombing runs, the Khans and Brotherhood add firepower and the Enclave Remnants arrive by Vertibird.

The Courier fights to the Legate's camp and confronts Lanius, or to the NCR's command and General Oliver. The result depends on the path: NCR victory, Legion victory, House's Securitrons or an independent New Vegas.

The battle is a test of the Courier's earlier work. The more allies the Courier gained, the stronger their side, and the quests that seemed side missions become decisive. It is a rare example of a payoff that depends on 40 hours of play.

Each ending has a distinctive tone. The NCR ending is hopeful but bureaucratic; the Legion ending is brutal and ordered; House's ending is polished and cold; the independent ending is uncertain and free. The ending slides summarise the consequences for every faction and settlement. They are as important as the battle itself, because they show the long-term effects of the Courier's decisions on towns such as Novac and Freeside.
