Just running out of ideas of where to go and explore before going back to the main quest. Any good gun fight ones? Just curious if there is any I have been missing. I generally do most of the NCR side quests. I want to try out some of my new weapons I picked up today.

Vault 11 was surpisingly deadly.

Not most of it, which I went through As mid-level courier. But I went back there a few days ago, and found the secret chamber .

Suffice it to say that it was a challenge getting out alive.

Yeah Vault 11 is great.

If you want to test out new weapons, the deathclaw promontory is worth a visit:

I assume you've already been to Black Mountain, but if not I recommend that too

I'm level 17 right now, i'd probably get [censored] if I went to the Deathclaw promontory lol i have never been there before though
