Cyberpunk 2077 was announced in 2012 as one of two large-scale, open-world RPGs the company was working on. The other was, of course, The Witcher 3: Wild Hunt, which was released to a rapturous reception in early 2015 (I am playing this at the moment and should have a review in the next week or so). After an early concept trailer and a bunch of interviews, CD Projekt declared radio silence, not wanting to hype up the game before it was ready.
Cyberpunk 2077 is - shockingly - a cyberpunk video game set in the year 2077. It is set in the Cyberpunk pen-and-paper RPG universe created by Mike Pondsmith in 1988, a world of massive corporations, oppressive corporations and people struggling for freedom and humanity in a world of massive technological and corporate power. The video game will be set in one city (probably Night City, a post-conflict Californian city and the signature setting in the pen-and-paper game) and possibly its surrounds, and will allow players to create their own character. They will be able to pursue a detailed main storyline, numerous side-quests and lots of optional activities. There may also be a multiplayer component of some description.
Given the impact of the Cyberpunk RPG and the genre as a whole, which inspired the Deus Ex and Shadowrun franchises, among others, it'll be interesting to see what the final result is like. CDPR may also be fortuitously tapping into a renewed interest and awareness in the cyberpunk genre, thanks to the recent release of Blade Runner 2049 (out on DVD and Blu-Ray next month) and the arrival of the Netflix TV series Altered Carbon.
It'll be interesting to see how in-depth the marketing for Cyberpunk 2077 will be, and if CDPR are going to give us a short, sharp campaign followed by release or something longer. In either case, the hopes for a 2018 or early 2019 release have risen according.
