In Lonesome Road 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 Fallout: New Vegas. Ulysses promises the answer as to why he didn't take the job, but only if you make one last journey into the hurricane-swept canyons of the Divide, a landscape torn apart by earthquakes and violent storms. It's up to you whether you take the job or not.
New Terrain - Travel through the tortured landscape of the Divide, a wrecked locale torn apart by storms and earthquakes to find Ulysses, the original Courier Six. Shattered canyons, abandoned missile silos, military bases, and destroyed cityscapes await.
New Enemies - Take on the Tunnelers, the vicious Marked Men, and Ulysses himself!
New Weapons - As you make this treacherous journey you’ll have a series of new weapons at your disposal, including the ‘Red Glare’ Rocket Launcher, a Laser Detonator that can be used to set off abandoned warheads scattered throughout the environment, and a variety of Pre-War ordinance including Flare Guns, Satchel Charges, and Shoulder-Mounted Machine Guns.
New Perks - Lonesome Road increases the level cap by 5 and includes an array of new perks and recipes such as Auto-Inject Stimpaks, Bitter Drink and Snakebite Tourniquet.
