1. There's a unique gun in one of DLCs for an explosive build, a grenade launcher.
2. There's a whole crowd of perks increasing damage and range when blowing enemies up - you need a custom character for the job.
3. There's crapload of things in the game you can find or manufacture to blow enemies up. Powder Gangers alone can provide enough dyna for a few good New Year parties.
4. The whole skill governs a wide variety of equipment, some ranged, some placed (I had Nightkin run into a mine I've placed in Repconn which was lots of FUN), some thrown.

Has anyone tried playing an Explosives guy so far? Can you realistically rely on what you find and use Explosives as your main weapon? Did you pick something else in addition to blowing up that would help save some dyna for bigger encounters?

I am considering a Melee+Explosives guy. Any tips on SPECIAL (8 STR for thrown range?), TAGs, Perks, and especially skill order and traits? Is it manageable to get all the perks for Explosives and Melee on one character?

My newest char is explosives energy weapons char. Have enough perk room for all 3 explo experts and all my wanted energy weapon perks and science guy perks too.

You don't need a DLC for this. I got a Grenade Launcher in the Vanilla (no pre-order bonus codes) game. In fact, if you know where to look, there is a Grenade Machine Gun. I have the gun, just have not found the ammo yet. Might have to spawn some so I can play with this thing.

Anyway, an Explosives character looks like fun in this game compared to FO3. Even without the grenade machine gun.....

My second run through I plan on doing an explosives/melee Powder Ganger.

The only problem I can see going only explosives is that there are times you don't want to blow 'everyone' up. Like if you are helping an assault or some such.

I hope I can pick up enough TnT without killing the Powder Ganger's for it as I plan on playing as if I was one...
