Fallout 4

In my experience so far, I have found a pretty fast way to level up. All you need to do is progress with the Minutemen far enough until you have taken the Castle. Don't worry, going this far will NOT hurt your reputation with any of the other factions. Now, after you have taken the Castle, Preston should have gone back to Sanctuary (at least he did in my case). At this point, he will keep feeding you quests either telling you to go clear out a new settlement, or help an existing one in some way. Depending on your Int level, you can get a pretty nice Exp bonus from farming these quests. I have 8 Int and I am averaging about 150 exp per quest completed. Plus, all of the experience you will get from killing all of the required enemies in each quest. I have gone from 39 to 42 in just over an hour. It's not lightning, sure, but it's the quickest way I have found so far without breaking the game.

WAY #2. Alright, here's for you folks that feel you need to break the game to hit 50. It's simple, all you need to do, is get a decent sniper rifle (make sure it has a long scope, too), and join the Brotherhood of Steel. Set the game to easy and progress until you hit the Learning Curve quest. What the quest will have you do is protect a fellow Knight using your shiny rifle from the deck of a ship. What you WANT to do, though, is crouch and make sure you are HIDDEN. Once you are, your only goal in life should be to team kill the hell out of your friend. Make sure you are HIDDEN before each shot!!! What this does is, if you are UNSEEN, it will just end the quest. You can now go back to Quinlan and claim your 300 exp reward, AND you can do it over, and over again to your hearts content. You should get the 300 exp in all of 90 seconds per run. EASY level 50!

Happy hunting!

A couple of shootouts from the comments here:
Both Illustrious Yeti and South Park TFBW have added that you can get the idiot savant perk, and rank it up so you get the 5x bonus, and right before you turn the quest in, save and turn the quest in. If you don't get the bonus, you can reload and try again to get the bonus! Handy!

On the other, brighter end of the spectrum, A Giant Radroach suggests that you can also max out your Int, get the night person perk for even more intelligence, wear the Vault Tec lab coat for even MORE, and sleep with your lover to get a pretty consistent exp bonus to make it go a little faster. So many options!

That's it.

Cheers.

Reaching level 50 should come naturally as you play through the game and earn the rest of the achievements. However, if you are impatient like I am, you can simply duplicate shipments of copper and build statues to boost your experience like crazy.

you will need to find a copy of picket fences which can be found in Saugus Ironworks


now that you have the statues, follow this video to learn how to duplicate shipments of copper to boost your xp to get those few extra levels you need


make sure you quicksave after every few duplications so you don't need to keep buying more!

samsaBEAR pointed out that the more shippments you have, the quicker and easier it is to duplicate as you do not need to press the buttons as quickly

Okay I have a fantastic strategy here that can provide 10k XP in a minute.

What you must do is 1st of all acquire the Statue addition of "Picket Fences" this can be found in Saugus Fireworks on the floor in the room with the big heavy Gunner called Slag.

After this you're gonna need to create a cabinet and every single item in your workshop and your junk from your inventory put into the cabinet.

Right now all you need to do is acquire a Shipment of Copper (more the better)

Once this is in your inventory this is a duplicate trick, quicksave... Go into your workshop and press Y X quickly, what this will do is times the 25 Copper you get in a shipment by how ever many you have, keep saving when you get 500 more as sometimes you can be too slow and it will corrupt your shipments of Copper and you'll need to get more.

Please note you can only do this in the build workshop not the weapon/armor etc ones.

Once you have enough Copper I would recommend 10k which currently gives me 4 levels, find an open space like Drive in or the Island and keep making statues in a long line, this only requires Copper, then once you've hit your limit you should be flying on XP, just delete all those statues and start over.

Max Intelligence gives 30XP per statue and if you have the Lover's Embrace Perk from Romancing Piper it hands out 35XP per statue once romanced.

Hope this helps!

I've just tested and you cannot do this with just 1 shipment so you'll need to acquire 2, shops are unpredictable so you can actually duplicate any item by setting Dogmeat as your companion, if you drop the item and ask him to pick it up, try pick it up exactly when he does and you'll have the item in your inventory while he drops the duplicate.

Thanks to ST0NE C0LD ET for adding this:
"Wanted to add that Arturo in Diamond City sells shipments of Copper and red rocks every 48 hours

Also for a faster XP grind instead of deleting all of your statues once you've filled your lot, single one out and then mash X and A on it repeatedly to begin a Scrap/Build loop that is lightning quick!"

a good way to get good xp is to get the idiot savant perk to rank two and save before you turn in any quests if the perk doesn't proc whenever you turn it in just reload your save and try it until it procs for you 5x quest xp is a pretty fast way to level up

Here is an exploit after the latest patch. I am not the founder of this exploit and a ton of videos on YouTube will show you how, but i'm posting this for people like me that better like text guides. So i'm giving full credits to the founders of this glitch.

So here you go, the first thing you'll need is the Automatron DLC.

1) Go to a settlement with a companion where you have no power or other items as such placed and take the most junk you can transport in your inventory so you can craft items there.

2) Once there build a Robot Workbench.

3) Ceate an new Automatron and craft a new Torso for it. For this case, I used the Assaultron Torso.

4) Now this step is really important. Click back on the Protectron torso on the top of the list so the mod you created goes in your inventory.

5) Craft a container and place it beside your red workbench.

6) Take everything in your workbench and place everything except your Robot mod in the container.

7) With only your Robot mod in your inventory, stand next to the Robot Workbench.

8) Call your companion and command him to go next to the Robot Workbench.

9) Trade with him and as soon as you click trade, enter in the Robot Workbench.

10) Now if you did it well, your screen should be messed up with both the trade and the Robot mod options overlapping on each other.

11) Click on the Assaultron mod.

12) Now spam the hell out of Right on the D-Pad and A.

You will keep getting XP as long as you spam.

If you get out of the Workbench and are willing to do the glitch again, you will have to create a new Assaultron mod to have in your inventory.

There you go! Fast and easy way to be level 50!
Hope you enjoy and here's the video I used to do the glitch.
