Anyone have any suggestions as to how to make a good techie gunslinger? backgrounds, schematics etc. all suggestions accepted
Don't bother with gunsmithy. You can steal all guns you need with fate points (Sammie White in Tarant has a Hand Cannon - be sure you snag it as soon as you can). As for backgrounds, it's not necessary but good choices include Bandit, Raised by Orcs, Raised by Monks and perhaps Miracle Operation (if you can stand the devastating effect it has on your physical stats, that is). I would also suggest a point in Explosives for the Bullets schematic. What can I make up other than that? Oh yeah... be sure you learn how to make charged rings, you will save points you would had dumped in Dexterity if you do that. If you bring Magnus along, there is no need to push PE higher than 16 - he can make you eyegear. I'm sure there's more, but I'll leave that to others.
Since the game is too easy anyway, personally I think a lot of the fun is in making all the different types of guns in the learned and found schematics and trying them out, so I would take Gunsmithy, especially since I also like to find other gunslinger NPCs and make different types of guns for them as well. If you are a powergamer you can force your way to a certain place and get a free mechanized gun early on, which is a devastating weapon. Seems kind of pointless though. Recently I was playing a gunslinger (on Hard difficulty) and happened to find the schematic for mechanized gun in a shop fairly early in the game, well I built it and it ended up making the game so easy I lost interest in that character.
