Welcome to Explorer, a modification for Fallout: New Vegass that aim to expand the original game with a lot of new areas, items, weapons, quests and much more. As the name suggest the mod is focused on exploring discovering new places that are not tied with the main quest.
"I Don't Think So" is a new custom unique weapon that can be obtained by finishing the new custom quest Treasure Hunter.
I know New Vegas already have shotguns, but this was more for me learning how to model and texture better. I know is not perfect, but be gentle is my first ever shotgun model :p.
By the way this isn't just a normal shotgun, but it have aprecision mod already built in and a "clip" of 6 shells, instead of 5 of the normal New Vegas shotguns, it have high durability, but it cost a lot to repair it.
