Basically a continuation of Cyberpunk 2020/v2, while skipping over 2030/v3 (for reasons like... uh... not being the popular version and people not liking what Pondsmith/crew did in 2030). The only carry over from that is the "4th Corporate War" happens and... a nuke goes off in Night City.
Unfortunately, this is nothing more than a "demo"/one-shot demo kit. The rulebook is VERY SPARSE for something that is meant to advertise the Core Rulebook of RED/v4. Netrunners have a core-skill, the others are "oh, it's in the rulebook [which isn't out yet currently lol!] lol! Sorry!"
The lore-book is alright, but just as sparse. It DOES however contain a one-shot adventure, which is more than I can say Shadow of the Beanstalk/Genesys does (read: Genesys doesn't include that).
Is it worth the $20 or so that DrivethruRPG is selling it for R. Tali wants? Well... no, IMO. If you're a new player, this isn't really going to give you much in the way beyond a one-shot adventure that doesn't even explain a lot of the rules too deeply and you're better off waiting for the actual Core Rulebook to hit. Maybe then the One-shot will be included there.
This feels more for the 2020/v2 players that want to "update" before Cyberpunk 2077 launches.
