Alongside the release of Phantom Liberty on the 26th September, Cyberpunk 2077 will be getting a massive free update that makes sweeping changes to core gameplay systems. CD Projekt Red is straight up calling this '2.0', which should give you an idea of how significant the adjustments are.
You can see some of these overhauls in the gameplay trailer embedded above. Just to cover a select few, skill trees have been totally reworked, a proper police system exists, and cyberware operates differently. The update also brings new vehicles, weapons, missions, and open world activities.
If you're hungry for more info, CDPR will be hosting a gameplay livestream on the 24th August.
