I find it unlikely since we know

Black Mountain had 2
Cottonwood Crater was 1
Mesquite Mountains Crater had 1
and Nellis had at least 2 more likely 3

it accounts for all the nukes

Presume you are referring to Searchlight airport? Old Nuclear Test Site is just uphill a ways west of there, and of course there's the Legion-created radiation source in Searchlight itself.

There is also the distinct possibility that the devs placed some of the 7 nuclear strike locations at spots like Searchlight airport, but were either too careless or lazy to bother making the surrounding area reflect what it *should* have looked like if a nuclear missile had actually struck there. Only they know the answer to that.

Yeah, I'm not convinced that Nellis was even hit, let alone 2 or 3...

There were duds.... lol.

Well Pete says it was also you must remember the actual base would be far larger then the fenced in area in game. the nukes that hit nellis may have been as i have said before outside the game world.

If you go outside the playing area there's a large crater just east of Nellis.

Jst curious -couldnt the nukes of been radiation based weapons?-instead of just big boom?
