Right now zombie powder is a funny chem that few know about. But it is really hard to do really fun RP with it. This is for a few reason.
1- It is hard to make. Mainly cause it need carpotoxin in large amounts. Even using around 100u of carpotoxin you can only make 40u of zombie powder. This would not be an issue if getting carpo toxin on mass did not require you to raid kitchen for 50 pounds of fish.
2- It hard stuns you. Unlike sedative chems such as soprorific that apply confusion over time that leads to sleep. This chem just applies knockout. This is okay but if you made it work like soprorific it opens up the door to some master class RP. Cause with chems like ethely or methly you can ressist the sedative effects.
This would allow you to look dead but still move. Imagine the kind of stuff you could do to mess with MP’s. It works on xenos too except they can still slash you. Imagine CIA or whatever using this.
Not to mention the cool surv stuff you could do. Rush hospital and get some fake death pills. Then dress up as one of the static corpses on the map and fool everyone. The main counter to this would be for runners to just double tap you.
