You need to add it to Steam before Steam can download it.
I recently bought the Fallout Trilogy and it performs well on Vista.
Yes, they bought the rights to the Fallout Franchise from Interplay, Obsidian entertainment is developing Fallout : New Vegas, they don't own the rights, and the game is being published by Bethesda.
Bethesda Softworks. They also have made The Elder Scrolls series and are licesend to make as many fallout games as they want because they bought the series.
Skyrim was developed by the same team that created Fallout 3 and Oblivion before that. The Fallout series was first developed by Interplay - they brought out Fallout 1, 2 and Tactics. Fallout 3 was developed by Bethesda, however, Fallout: New Vegas was developed by Obsidian Entertainment, and published by Bethesda.
The best option is to get the Fallout bundle which can be purchased on Amazon.com. As a side note, the original company that made 1 and 2 filed bankruptcy and so the games can no longer be bought from their site.
The Sierra Madre is the location of the Fallout New Vegas DLC Dead Money. This DLC cannot be bought anywhere on console other than live.
if you bought the add ons on disk just put the disk in and do what it says.
Halo 3, Cod4, Cod5, Fallout 3, and Gears of War 2
no, i have it. i bought it from EB games plus separately all the add-ons so i don't know where you get that idea :D
Not unless you have an add-on hdd - just bought it and found out I couldn't play it without one!!
Try going to the store you bought it from. Tell them what is happening, and maybe they will walk you through it. :)
I think you mean the 'Anti-material Rifle'. It can be bought from the gun runners, south of the strip or taken from some veteran NCR rangers.
