New DLC is available for Fallout: New Vegas! In Fallout New Vegas: Dead Money, your life hangs in the balance as you face new terrain, foes, and choices.

Welcome to the Sierra Madre Casino! The casino’s mythical contents are lusted after by desperate wasteland scavengers, who tell stories of intact treasure of the old world buried deep within its vault.​

As for Horror: Things get scarier and tense when you can't escape, no one's coming to help you, and your resources are limited, and Dead Money was built around this. Watching the YouTube playthrough footage where players started re-appreciating chems and Stimpaks made me happy - these things are miracles of medicine, and they should be viewed as such and appreciated for that in the world of Fallout. One issue I've always had with Fallout is it's really easy to amass a lot of chems and stims, so much so you lose the sense of wonder and relief when you get these items, and I feel situations like in Dead Money can give you a new appreciation for food, crafting (we put a higher priority on crafting and supplies to make crafting worth more in the DLC), unconventional water sources, and the joy at finding an otherwise common chem in the Mojave takes on a new level of preciousness when you're in hostile territory. One YouTube video showed someone finding Buffout - and to hear them say, "thank god" and hear genuine appreciation for finding something so rare is exactly the kind of value I want people to attach to these items... usually people seem to care less when they find Buffout, but it all depends on the environment context. I want players to attach value to them again rather than, "oh, more Buffout." It's BUFFOUT. It's a STIMPAK. Your character should be OVERJOYED to find these things, each and every time.​
