I really tried to solve it on my own without no guide but I got a little disappointed with that obvious code, this quest could very well have been more well made.

I thought it was fine, I had a hard time following the freedom trail at first. once i figured out what the letters and numbers were meant to be used for, i had to go back and re check all the man holes. then mentally face palmed when I realized what the code was. My final thought though is that the code is what it should be, that way upon replay its not necessary to go through all that business of checking manholes again. the pass word is memorable, won't forget it.

I figured it out before I even had the second letter. Too easy.

I enjoyed following the trail.

It starts easy, but then is easy to lose track of under rubble.

As I've walked the Freedom Trail in real life, I know kind of the direction it was heading in, and found it again.

As far as the lock was concerned,

sure it took one letter to suss the phrase...

The first one I found was at swan lake it said 7 A i thought it meant something happens here at 7:00 am so i found a chair nearby then 7am came and nothing happened then i just followed the red line and i was at the code area i didnt know what i was supposed to put so i just looked it up.

I stumbled across the final location before I even knew about the red line to follow when I was exploring on my second character. The code was pretty easy. Once you find the first letter by just randomly doing it the answer is fairly obvious.....maybe to obvious as my first reaction was "Seriously? Did the same guy who did Skyrim's pathetic puzzles do Fallout 4s as well?"

I want to see way more of this is Bethesda games. achieving the solutions to these types of puzzles gives a great feeling of satisfaction. They should incorporate this into quests for very rare items and armor and I feel fallout or the next elder scrolls will be perfect.
