Dr. Earnheart was like yeah bro take all these drugs!! but I can't pick them up. I hear people talk about using drugs but I can't find any elsewhere. How do I get them?
GT: F3rocious Panda
After a certain point in the game, you can get these little 'drugs' in the cave where your friends are that take you through flashback sequences. They shouldn't be too hard to find.
People really need to stop complaining about the inclusion of online passes...
You have to craft syringes that give you special abilities. The recipes are unlocked as you play and you will get a prompt when they do. You have to have the right amount of the various plants in your inventory in order to be able to make them. You can assign up to 2 types of syringes to your left or down D-pad for quick access. In the crafting menu, under syringes, you can highlight a category, like hunting, or combat, to see which recipes you have unlocked, and what ingredients are needed.
