Im pretty much NOT close to that.
I found a horde in a bar, next to a gas tank. So id start off with an attractor, once they gathered, id throw a grenade. When the rest followed, id have them chase me to the tank and have a proximity mine (i just acquired the skill to make them) blow up the tank. It hardly made a dent.
Ive put in so many hours and im STILL at trust level one at Iron Mikes. Not complaining, but mother of god, i may as well skip farming for trust cuz that shit doesnt do shit and ive got the skillz to double up herbs and meat.
I have enjoyed taking out the nests but im never totally sure im done there. Id look at the maps and see how many are left in the Legend, but they dont mark the houses, so ive gotta assume those areas are clean. Now that im feeling im only getting my feet wet in the game, i fear theres just not a lot of nests in the game.
