I'm still on my first character. I'm only level 27 and I'm thinking I'm going to get to level 50 complete the main quest and then start a fresh character.

It's somewhat of a self imposed cap to ensure I don't experience everything first play through.

I like the idea of the syringe and I'm sure mods will give more and more effects in the future.

For my next char I was thinking of making a syringe based player using no other weapons but relying heavily on explosives, hacking, robotics and taming/commanding others to do my dirty work. No direct involvement. Set up the pieces and let them kill themselves.

Anyone play anything similar to this? Is it viable?

Ammo would be a problem for the syringe gun.

you lose a lot of experience not killing things yourself and you have to get to a higher level than what you're fighting to be able to control it. It could be fun to play with but difficult for a main focus and the dart gun doesnt have a high rate of success. Problem with thieve type characters too is until you get to a boss and then you have no means to stand and fight. You'll need to craft tons which would be easier late in the game. I'd say get to 50 then you have the freedom to do as you want. But I'm close to doing everything in my first playthrough, the levels just keep going. I'm level 70 I figure I can put another 20 levels in to get melee and pain train. I've even started trying to get through each factions main quests. I can buy out all the resources from docs and traders to make ammo for the syringer and have tons of junk to do it now.
