Normal difficulty level.
I’m not particularly good at these games but enjoy the landscapes. So far, I’m just exploring and have only done a couple of quests. I couldn’t even imagine taking on a deathclaw on survival level. I think I would need to find some new underwear as well as a ton of stimpaks
Hee-hee!
On my survival run, basically level 1-2 and with armour and hp that made me likely to be killed by a stiff breeze, I stumbled across a radscorpion immediately after Concord, then while carefully trying to get to the car plant an hour or so later and not much more experienced, I saw a deathclaw in the wild 'patrolling'* that had just spawned in, thankfully just wandering off away from me. In both instances, flight and hiding was the only safe option
.
There are a number of places where deathclaws are more or less guaranteed to appear when you reach them....but I'll leave that for you to discover
. Oh and there are the guaranteed spawns of really nasty Behemoths (scary), Mirelurk Queens (very scary) and assualtrons (brown trouser time, at least for me, they are
evil!)...
Oh and when you've got comfortable, built up experience, good guns and you feel you can take on everything, raiders called
rust devils start to appear. I'll again let you figure out if they are nice or not....
p.s. look out for an UFO actually crashing! I forget what causes it to occur, but you actually can hear and see it...
======================================
* Deathclaw in the wild is much more dangerous than the first scripted one you meet, as you are given items to help you defeat that latter. Plus you can hide in the shops!
