Synopsis
Humans can perform biological augmentations to strengthen or harm them to perform certain duties. Sometimes, these augmentations get out of hand and the augmentation completely destroys all biological data within their body, therefore causing the person, now dubbed a "psycho," to kill everything biological (meaning humans.) After this happens, a "psycho squad" must step in and take action to cure (read: kill/recruit) said psycho.
The trailer demonstrates a portion of this when the female they went in to cure was recruited to their force at the end. (NOTE: Everything stated above this is regarding the fundamentals of the card game and the new release)
Game Mechanics/Gameplay
Regarding the mechanics of the card game, Cyberpunk 2020, players can use augmentations to strengthen or harm them in order to advance in the game's skill-based RPG atmosphere. These augmentations will lower the Empathy of their character, representing their disconnections from their biological self and transcending to their augmented state. This will, in turn, create issues and advantages both, leading players to difficult decisions to make.
It can be safely assumed that its modernized child will be based upon the same factors and building blocks, however, CD Projekt RED (the developers) have stated that Cyberpunk 2077 will be a non-linear RPG rather than its card-based predecessor's approach.
