How to unlock the Big Pharma achievement in Fallout Shelter - Definitive Guide
You actually need 100 Stimpacks AND 100 RadAways from quests, not 100 of both.
Ive found myself stuck on 80-90% for a long time now just to how few RadAways you pick up during quests.
The only tip I can give is go out on quests with a full 25 stimpack and 0 Radaways and that seems to force the game to give you atleast 2 a quest.
Getting the 100 Stimpacks is simple, I get at least 5 every quest.
When managing your dwellers as they loot and plunder on quests, each time you kill all of the enemies in a room you want to make sure that you loot it properly. You do this by pressing a few times to loot all of the crates and enemies that can give something useful in the room. Having a dweller with a higher Strength will make it where you can open more chests that you find. Enemies and chests will sometimes give you Radaway and Stimpaks when looted, so just keep doing quests and looting rooms. Once you have looted 100 Stimpaks AND 100 Radaway, this achievement will unlock.
During quests you will collect a lot of stuff, including Stimpaks and RadAway. You can find them on containers and after killing enemies so be sure to visit and loot every room before finishing the quest. Unfortunately, there's no easy way to track this trophy.
