I had been playing a purely-explosives character up to level 15, in which I would never use a gun to kill someone (maybe a missile launcher, but rarely, because the damned thing was so heavy), only grenades, mines, and a melee weapon. Naturally, due to the scarcity of grenades, I spent alot of time trading tech with the Outcasts. Using FWE and WMK, I always kept a pistol fitted with a laser sight and silencer to blow up anything that I suspected the enemy wasn't going to detonate themselves, a bunch of junk to craft grenades whenever I found a workbench, about 80 grenades and 30 mines at any time, and a super sledgehammer (weapon's ability to knockdown > everything else). Now I'm just playing energy weapons only, which is awfully hard, I'm finding, due to ammo scarcity and costs.
