Ok, so first of all, you need
150 Organic Samples, not 10. And organic samples = loot from killed animals. A good place to farm these is in the Village map, in the left side of the map right at the fast travel point. In my video below, I use the pistol because there have been times when I wasn't being able to loot the wolves. I don't know if the weapon is very important or if it's just another bug of this game.
So, you can either kill all 3 wolves and after that, use a grenade to kill yourself or sometimes, there's a car on the road passing by, so just jump in front of it and you're dead without wasting any grenades. Or, you can leave a wolf alive and let him kill you. It's all up to you on how you wanna die
After that, just rinse and repeat. If after reaching 150 organic samples, you didn't get the achievement, just kill yourself again
Happy achievement hunting and please leave a comment if there's something that I forgot to mention or if you leave a negative vote
