Max Pears, Level Designer on Cyberpunk 2077, spoke about this system in an interview with ShackNews, and went into some interesting details, going on to give examples for what sort of stuff this system will allow you to do and what kinds of opportunities it will open up. We have this really cool class system, Pears said, where we have things like Netrunner, Techie, and Solo, but what we do is weve got this fluid class system. Each of these is gonna have different abilities. So a Netrunner can hack into peoples brains, [like] in the [E3 2018] demo.

You see that we knock out a guard, and we hacked into his brain, and this unlocks sort of different routes for the player, he continued. Each class is gonna have some great abilities. So the fact that youre going to be able to put your own mix of these classes together to make your own cyberpunk, thats gonna be awesome. We look forward to that.
