As a genre? I would say no. Cyberpunk is usually described as a capitalist dystopia in which a handful of companies supersede government powers and wage wars against each other beyond the concepts of national borders. In addition, cybernetic enhancements become commonplace, as a way for companies to extract more value from their workers. Cyberpunk stories usually are about groups rebelling against the system through organized crime, who ultimately fail to escape the underlying system of capitalism, doomed to repeat history time and time again.

HL2 falls in none of the genre stereotypes. While it is dystopian, it’s not capitalist, so it’s not “punk” and it isn’t “cyber” either because of a lack of commonplace cybernetics.

I can recommend “Encased”. It’s a CRPG that’s heavily inspired by Fallout gameplay wise, but it’s modernized a lot (in a good way). It has its own unique story and setting which are amazing to explore

Encased is a CRPG, heavily inspired by the classic Fallout games, bringing it’s mechanics into the modern age. It’s story is based on the classic book “Roadside Picknick” (known for being the inspiration of the Stalker series) and is very well written. It has a story narrator, similar to the Divinity: Original Sin games and a very in depth character creation. At the start you choose a department of a research company to work in, which will change the way you interact with many characters, adding some replay value. Anything more I could say would be a spoiler, but the entire beginning (first half to one hour) is an absolute banger.

It’s my favorite indie game of the last few years and at the time of writing this, it is currently 90% of on steam, an absolute bargain
