How does one get “Young Spirits” achievement

So I did a bunch of testing on this tonight. This is what I have found:

• The nutshot and the testicle assault do not have to be done on the same enemy. The achievement simply pops after you have done each activity the first time. I killed a gang member via testicular assault without doing a nutshot on him and acquired the achievement.

• You need to actually kill the enemy via testicular assault in order to get the achievement. You'll know when you have done this because you'll see a popup for Respect with the name Testicular Manslaughter. Hitting an enemy twice with a testicular assault will get this done.

• It does have to be done on a male character. I tried doing testicular assaults on female gang members, and while I was able to kill them and they did the animation, I did not get credit for a Testicular Manslaughter.

From what I have been able to determine, based on previous times this question has been asked on the steam user forums, Farce is not required for this achievement. Which answeres your question there.

In most cases the users found they accidentily skipped some dialog or scenes, in the prolouge or at some point through the gameplay. The only way to get it in this case would be to play through until you find out what you skipped or missed and get the achievement that way.

While this answers your question, i wish i was able to help you narrow down what part you missed but I dont believe there is a way to check that.

Good Luck
