What shotguns has everyone found? I'm planning on skewing my weapon perks towards shotguns as I get into the higher levels. So far I've only found pump actions, double barrels and combat shotguns. Combat shotgun is solid but not as much opportunity to mod it out like I can the pump action or double barrel. I've only found one "unique" named weapon up to level 22 so far, which was a quest reward (a 10mm SMG).
I'm having a decent time just doing some exploring and finding different quests, but more and more the combination of eternal weight struggles and bugs is wearing on me. There are so many quest scripting bugs that involve finding or interacting with a quest-related object before you hit a certain step in that quest. I've also run into a few cases of the classic Bethesda Fallout AI alerts multiple floors of enemies to my presence and results in a ridiculous amount of enemies funneling into one point. You'll almost certainly encounter this in the Charleston capitol building (or connected DMV); be very careful if you enter from the DMV side where an Overseer holotape step is picked up because if you engage in that first room you'll get aggro from about ~20-30 super mutants within the connected building. Stay near the entrance so that if you think you can't handle the swarm you can just exit; if you don't it only takes like 8 super mutants filling up that space to prevent you from being able to reach the doors.
Some enemies feel like they are getting a little spongy around this level. When doing events solo (with those big event monsters being level 30 typically where I'm at) it has mostly been an exercise of finding whatever spot will allow you to shoot without them being able to fight back. They have rewarded some nice loot (Cryolator, Gatling Laser) but nothing I actually want to use so far. I have come across some power armor already but wound up stashing it, I don't really have much desire to use power armor and really hope it doesn't wind up being required down the line. There's too much micromanagement in this game as it is.
