You can grab one early from Fens Street Sewer (don’t bother killing the glowing one at early levels), and sufficient ammo is available from vendors as early as level 8 from what I’ve seen. The flamer not only solves the problem of getting over the early hump but can be a legitimately solid backbone of your heavy weapon build in the long run too. Undoubtedly the biggest issue with heavy weapons builds is simply getting them off the ground. Tip 1: The flamer is fantastic, and pretty much your only option early game.

Accordingly, I wanted to share a couple of my learnings and experiences with anyone else who may be interested in trying a heavy weapons run of their own sometime. I’ve been messing around with a handful of different approaches to a heavy weapons build in FO4 and was finally able to hobble something together that not only works, but is genuinely good. I’ve had a soft spot for big guns ever since FO3, trying to make some rendition of the archetype work in all the games since then.

Made some minor edits to my original piece, and hopefully some of yall find this info interesting or helpful! I posted this write-up to the Fallout sub some time ago, and just recently found this sub.
