Fallout: New Vegas Add-ons

On October 18, 2010 Bethesda Softworks announced that downloadable content will be available for New Vegas, in keeping with its predecessor Fallout 3.

According to a since-deleted blog comment, Scott Everts was responsible for hiding DLC hooks in the base game. This was seemingly confirmed with the presence of a "nvdlcgraffiti" folder in the game files, containing graffiti with filenames including "nvgraffitisierra" and "nvgraffitihonesthearts", hinting at Dead Money and Honest Hearts, respectively.

On May 3, 2011, Bethesda released an article on their blog, confirming Honest Hearts, Old World Blues, and Lonesome Road as the next three add-ons for Fallout: New Vegas.

Each of the four add-ons increase the level cap by 5, which in total will increase the maximum level to 50. However, a trait will be available in the Old World Blues add-on that will allow you to limit the cap to level 30 (or current level if you’re already over 30).

Pre-order bonuses
Players pre-ordering Fallout: New Vegas from selected retailers were granted access to special pre-order bonus packs, containing exclusive equipment to make the earlier stages of the game easier. The list of bonus packs is as follows:
 * Caravan Pack
 * Classic Pack
 * Mercenary Pack
 * Tribal Pack

Dead Money
Dead Money involves working alongside three NPCs to find the treasure of the Sierra Madre Casino and adds new achievements, perks, terrain, enemies and decisions for the player, as well as raising the level cap to 35. It was released on December 21, 2010, for the Xbox 360, and on PlayStation 3 and PC platforms on February 22, 2011.

Honest Hearts
Honest Hearts takes you on an expedition to the unspoiled wilderness of Utah’s Zion National Park. Things go horribly wrong when your caravan is ambushed by a tribal raiding band. As you try to find a way back to the Mojave, you become embroiled in a war between tribes and a conflict between a New Canaanite missionary and the mysterious Burned Man. The decisions you make will determine the fate of Zion. It was released on May 17, 2011 on the Xbox 360 and PC platforms. It was later released on June 2 (NA), and June 5 (EU) for Playstation 3.

Old World Blues
In Old World Blues you will discover how some of the Mojave’s mutated monsters came to be when you unwittingly become a lab rat in a science experiment gone awry. You’ll need to scour the Pre-War research centers of the Big Empty in search of technology to turn the tables on your kidnappers or join forces with them against an even greater threat. It is set to release simultaneously on all platforms in June, 2011.

Lonesome Road
Lonesome Road brings the Courier's story full circle when you are contacted by the original Courier Six, a man by the name of Ulysses who refused to deliver the Platinum Chip at the start of New Vegas. In his transmission, Ulysses promises the answer as to why, but only if you take one last job –a job that leads you into the depths of the hurricane-swept canyons of the Divide, a landscape torn apart by earthquakes and violent storms. The road to the Divide is a long and treacherous one, and of the few to ever walk the road, none have ever returned. It is set to release simultaneously on all platforms in July, 2011.

Future add-ons
No further add-ons have been confirmed to be in development other than those listed above. Directly above the snow globe stand in the Lucky 38 presidential suite, there is a shelf meant for snow globes from add-ons. The shelf appears to have four spaces; one for each of the confirmed add-ons.

Jason Bergman has stated that one thing that will not be appearing in an add-on is the ability to extend the game past the ending, á la Broken Steel.
