Good suggestions. 1)Best weapon is the Browning LMG. It is good for mowing down enemies and bosses. It does descent damage and has a huge clip and very fast fire rate. Once you upgrade it to the minigun it becomes almost unstopable, even against the Super Mutant Boss, it only takes fifteen seconds to kill it. 2)Abilities you obviously need, hacking, eagle eye, sprint, health, leadership, etc. 3) Whenever you find a civilian add it to your squad. At the end of each day each one gives you 100 gold which is more than two upgrades for the factory. And so you will be like a money machine. 4) Factory upgrades aren't worth it. +50 gold at the end of each day isn't worth a 7% threat growth rate. The civilians will easily make you enough money. 5)Minigun is the best outpost upgrade. It mows down enemies quickly.
The sleep skill is really overpowered when battling bosses because it gives you almost an unlimited amount of time to debuff the boss and buff your allies
