And...prepare for anti-climix!!!!!!

The entire room was caved in with nothing in it.

There is another bunker.

There's a few bunkers. 2 of them have nothing (I think), one has an NCR trooper, and one is the Brotherhood.

Also, if you're thinking that caved in room was empty, you didn't look hard enough.

Actually, there are at least 3 bunkers.

Those sneaky Paladins!!
