This guide is for one specific part of Zen with multiple achievement props. If you are trying a full run with either two of the achievements “The Rarest Specimen”, “The Plan”, and/or “Pepperoni Precipitation”, Then this will be for you! If not then it won’t be a problem at all and you can skip everything about this small walkthrough.
The Prop Areas (Simplified)
Pepperoni Precipitation (The Pizza Box of Dr. Horn’s) Chapter 11: Questionable Ethics; in the cafeteria.
The Plan (The Cyanogen) Chapter 15: Zen; Inside the desolated research bunker.
You must also have satchel charges in hand as these will be important in getting the items in question to its destination.
While it is blocked, the power source, or what I like to call, the Chuthulu Heart, is just around the corner in crowbars length, but the problem lies when learning the area is a one-way jump, making it impossible to legitly go back to the original area.
Once this is done, you must detonate the satchel charge, grab the item, and fling yourself towards the other area. After that, you will need to be quick as the hat will be on the leaf, but it will be rolling slowly down to the depts of space. Place down the item (Whether it be the Cyanogen or the Pizza Box) and quickly grab it before it falls. And if everything was successful, you have completed this trial.
While this will take multiple hours just to get to this point, it is worth mentioning as it took me around an hour just to figure out the plan of action on this part. I hope this really helps someone in need and gets them through the tough problems this game can make at times. Enjoy and hope I was as helpful as I could be!
