Carried Stan's Load to Completion (Secret) Achievement Guide)

To attain this missable achievement, one must speak with Stan after obtaining the jetpack from the pawn shop. When you leave the store, turn left and go down the stairs towards the restaurant with the giant blue rat. You will bump into Stan who covered you in yellow liquid earlier in the game. He will try to sell you a "gallon of alien c*m". Go against your intuition here and purchase it from him. Now, simply forget about it and continue playing the game. The achievement will pop once you finish the main storyline. Don't worry about losing Stan's load as you play through the rest of the game. There is no way to either drop or sell it.



I wonder what the yellow liquid was that Stan covered us in in order to enter the G3 academy...?
