Radio Pack

Radio Pack is an item that can drop from Captains. Its main significance is as a loot reward tied to that enemy type, making Captains the relevant source if you are trying to obtain it.

Because the only confirmed acquisition method is a chance-based drop, farming Captains is the practical way to search for it. There are no additional documented uses, crafting inputs, or alternate sources in the available material, so its value in play is primarily as rare enemy loot.
