From what I can tell Buttons has a standard hunting rifle as a weapon with unlimited ammo. Not that Buttons is gritty or raw in most other ways, but I find that particular bit of realism refreshing.
I actually consider this a plus, mostly because of how many overpowered companion mods out there with super-powered stats and weapons. How about I tag along? Tuffle parasite xenoverse 2 modīuttons works for the Minutemenbut has no issue with your working with any of the other factions. His intro dialogue is short and to the point. The voice work included definitely puts Buttons ahead of most of the companion mods on the Nexus that are either un-voiced or poorly voiced, however.
