This is a collection of different development and memory-altering drugs, which can be used for the purposes of enhancing gameplay and story in Firk.

Each of these has a different effect, which will be shown in the game. The most important thing is that these work like the development and memory-altering drug, except that they also work like a regular amnesia-inducing drug, and the effect will be shown in the game.

It is worth mentioning that these are not a true reflection of the real world. The world of Firk is not real, and the characters are not real, but they do exist in the game.
