Deathclaws:
there's a named sniper rifle, NOT the "reservist's", that knocks enemies down on a crit, so, sneak shot = auto crit, = automatically knock deathclaws on their arse, and easy to kill, hehe!
as a hint, you need 100 lockpick skill to get that rifle and it's West of Arefu...
Yes bottlecap mines are great vs deathclaws + dart gun.
Efficient way to do it is this:
Position companion tell them to "wait", sneak forward, put down mines, pull the deathclaw with dart gun, stand up, and run, so he follows quickly, as sneak can make them lose you at times.
By time it gets to you, mines and companion will have ganked it.
Another VERY good tip is: when playing if you aren't sure what will occur when you shoot an enemy, open a door or whatever, put mines down around places enemies may come from, say, side doors, or aorund your position.

The teddy bear in the cage is so cute...he waves at you, his friend, though....
Oh, there is an UBER named Chinese assault rifle in game: Xualong assualt rifle, iirc. ANd of course, the MIRV Fatman!
[sblock="xualong"]
Museum of technology, a terminal will give a message, and you have to find 3 terminals with #001, #002 and #003 and aswer, in any order and get all right
if done, go to place it says and find dead raider with chinese assualt rifle with 36 shot clip and +50% damage or so!
MIRV fatman is...sick, lol!! 8 mininukes in 1 shot!! Fire it up high so they spread out and slaughter EVERY damned thing!
find all 5 "Keller" tapes, head ot the national guard armory, go through it all, you come out in a seemingly pointless area up top, where oyu can only jump back down to the exit...there's a switch up there that opens up an area below, you NEED the keller tapes, all of them,to go through the doors.

Also, there's a satellite tower that, if you do stuff, will call down a multiple nuclear strike...
