Well, the teaser actually has a description:
The teaser shows how the Psycho Squad might acquire a new member.
The Psycho Squad specializes in combating "psychos" -- individuals who overuse implants and substances that boost or otherwise alter the human body.
There comes a point when they overdose on these innovations, and their bodies start to rebel against their biological body parts as well as all things organic around them. Simply put, they start killing people, who they now derisively call "meatbags."
When a psycho goes on the rampage, strange things can happen. There's carnage, and the psycho might be taken down by regular police, but they're not always able to get the job done.
When things spin out of control, they call in MAX-TAC (Maximum Force Tactical Division), popularly called the Psycho Squad.
So it DOES seem like there will indeed be a balance to strike between humanity and overuse of implants.
CDProjekt RED seems to have a good grip on the task, and they acknowledge issues they face and how they might deal with them. They also got Mike to discuss things with, so I bet this is gonna be pretty damn good.
At first glance it may seem that there’s nothing easier than creating a video game based on an existing RPG system like Cyberpunk® 2020. After all, we already have all the mechanics prepared and ready to use in the game. As simple as it sounds, there’s more to it than meets the eye.
The pen & paper game rules are designed to give players as much flexibility as possible. They are more like a set of guidelines which players are at liberty to bend to their liking. Improvisation, dropping rules or adding new ones is a common practice for pen & paper games. This principle applies not only to gameplay rules, like combat or skill tests, but also to character customization. Players are limited only by common sense, the agreement of the group and their imagination.
Video games, on the other hand, do not have that much flexibility. Every element has to be accounted for and carefully designed. Of course, modern AAA RPG games, like The Witcher 2 or the upcoming Cyberpunk 2077, can give the Player lots of freedom. But the underlying mechanics are adhering to very strict rules and if an action or option wasn’t implemented in the code, then the player will not be able to do it. The same principle applies to character customization – the player can do only as much as game allows him to. So if game designers decide that it is not possible to play as an ugly midget you will not be able to play one. Sorry Tyrion Lannister fans
This is why adapting pen & paper rules to video game is not as easy as it can appear at first glance. The flexibility of an in-person RPG has to be replaced with a strict set of rules. Every skill, attribute and game mechanic has to have a clear definition and place in the game. For example, the Cyberpunk® 2020 “Wardrobe & Style” skill governs the knowledge about the right clothes to wear, when to wear them and how to look cool even in a spacesuit. As you can see, this skill covers quite a big area of lore and can be interpreted differently, depending on the situation and the players. In Cyberpunk 2077 this skill has to be tied to a specific gameplay mechanic. And all of these mechanics have to be clearly defined so they can work well with other elements of the game and, at the same time, be easy to understand for the player. After all, we don’t have a referee or game master to explain or interpret the rules as you go. And, to accommodate your curiosity, yes, we have some really cool ideas on how to present aforementioned skill in the game. Regrettably, we’re not quite yet ready to spill the beans
For hardcore Cyberpunk 2020 fans out there, twiddling with rules in such a way may seem like blasphemy. But rest assured that we are working very closely with Mike Pondsmith to ensure that the unique feel of the original, paper game is preserved intact. Of course we may need to change some things, add new elements or even drop the ones that simply do not work in a video game (“Geology” skill anyone?).
Btw, I really dislike Deus Ex: Human Revolution. The choices in that game were utterly superficial and the setting quite dull, considering you didn't even get to see the riots in detroit apart from a couple of idiots who were around all along. It didn't play its cards well at all, imo.
