CD Projekt Red's first episode of Night City Wire showed off Braindance technology and one of its applications, which is basically small-scale Netrunning.
Braindance is a big deal in terms of Cyberpunk lore and it's very much like Netrunning, except you've no connections to the outside net. It's got quite a few applications, one of which you can see on the video.
Cyberpunk 2077 senior quest designer Patrick Mills explained that Braindance was designed way back in the early 2000s, as a way to record someone's experiences and play them back for someone else as if they're reliving them.
"It was originally used for therapy and prisoner rehabilitation, but by 2077 it has become this global media industry, including things like movies, mass entertainment and things like that, video games", he said.
Cyberpunk 2077 has different types of Braindance devices but it mostly deals with XBDs, i.e. Black Braindances. The type we've seen in the demo is a so-called Flatliner, which is the type of Braindance that has been recorded as the person died.
Players will run different investigations throughout Cyberpunk 2077, so they'll certainly use Braindance a lot. That said, it's not a collectible - it's solely a storytelling tool or as Mills put it, "a keyhole into the life of the residents of Night City".
Cyberpunk 2077's new trailer shows off Night City's districts, as well as the badlands, which envelop the city and as CDPR said, offer a different type of open-world content that's specially made to emphasize the feel of the Mad-Maxian desert region.
CDPR have branched out into animated series as well, in addition to the already confirmed comic by Dark Horse .
