One of the objectives you'll need to complete as medical officer Samantha Cooper in episode 5 of Directive 8020 follows on from an interaction where Anders asks you to help her get some sedatives for an "experiment" she wants to conduct. Not suspicious at all. If you've spent more time working on Cooper's "playful" personality, then you'll be able to agree to the plan. However, if you've been making sure Cooper stays professional, you may avoid this puzzle entirely.
Depending on your previous actions,as Cooper, you need to track down the three chemicals you have to combine to create a sedative. You aren't told what they are, instead, you're only given the chemical symbols. Unless your chemistry knowledge is up to scratch, this puzzle can seem a lot more challenging than it is. So, here's what you need to do.
How to find the correct chemical agents for Anders in Directive 8020
In the chemical cabinet, each of the three chemicals you need to solve this puzzle is linked to a number. This sequence in particular, and the number sequence you need to input into the keypad is 168. The three chemicals you need for Diazepam Synthesis are:
- Chloroacetyl Chloride
- Ammonia
- Dimethyl Sulfate
To the left of the cabinet, you'll find a poster showing the three chemical symbols of each. This makes it slightly more challenging to know what you need to use, especially if your chemistry knowledge isn't quite up to scratch. Fortunately, there are three posters around the room which show three different chemical symbols alongside their names, one being a chemical you need for the puzzle alongside two random ones, which help guide you toward the solution.
If you've got a notebook to hand, making a quick draft of the three you need definitely helps in this section. Even a screenshot does the trick. When you're face to face with nine possible chemical symbols in total, I found myself getting confused at which ones I needed and ended up inputting the wrong key code as a result.
Once you've punched in the correct code and combined the chemicals, you'll need to take it back to Anders. A cutscene will play, showing Anders taking the chemicals and you both reconvening in the wing to continue the objective before meeting back up with Williams. This marks the end of this storyline and puzzle, so you can crack on with the next steps of Ander's curious plan.
