to breath underwater you need to go to the boombers at nelis air force base and talk to their leader. She will tell you to go around and help people do that then go talk to her again and start a quest called "valore!" in witch you have to refloat a b-29. When you are told to do this you have an optional objectiv witch is to go and get a rebreather. the rebreather lets you breath underwater forever and you get to keep it after completeing the quest.
Occasionally Fallout: New Vegas will freeze, but not as frequently as Fallout 3.
fallout: new vegas 2 I've heard.
Fallout: New Vegas
Fallout New Vegas is the fifth installment in the Fallout series. It is for the Xbox 360, PS3, and the PC.

No, you can't get married in Fallout: New vegas, but you can have sex in the game :)
fallout new Vegas will be on PlayStation 3 and Xbox 360
In my opinion, Fallout 2.
Fallout New Vegas is all one game.
There are no drivable vehicles in Fallout New Vegas, unless added by a mod.
Nothing in New Vegas spoils Fallout 3. They take place in 2 completely different corners of the country. And New Vegas can not spoil anything for Fallout 3, as New Vegas takes place before the events of Fallout 3. Hope this helps! Also Fallout 3 is not a sequal. But lets pray for a Fallout 4
You get the rebreather in Nellis Air Force Base and you can use it to breathe underwater. You can either gather supplies to make it or with a certain science level you can skip this step entirely.
