The Fat Man should be an important part of any wanderer’s arsenal while venturing out into the wasteland. The Mini Nuke-launcher is a powerful weapon that can quickly turn a battle in your favour.
Mini nuke’s might seem like a rare commodity out in the wasteland but there are many places you can pick up some ammo for your Fat Man.
TIP: When confronted by a Super Mutant Suicider (those are the crazy mutants running towards you with an activated red glowing mini nuke in their right arm), aim for their head, torso and left arm. If you can put them down before they get close enough to detonate their nuke, they’ll drop their ammo, allowing you to pick up the sweet, sweet Mini Nuke for your own use.
