Just a few weeks ago, League of Legends released a new set of skins, named the "PROJECT" skin line, and created a promotional site and video for the release. The "PROJECT" skins are set in a future alternate universe in the world of League, and I thought it was very interesting to see how they imagined this cyberpunk twist.

Skyforge is a mmorpg that combines Greek/Roman aesthetics with futuristic technology, and has a "web" system very much like Sindrome's, actually. Although I wasn't really fond of the gameplay, which was sometimes tedious and grindy, they way they mixed ancient mythology with science fiction was something I really liked.
Cyberpunk has been a genre that doesn't seem to be explored much by major developers (except in specific games like Mirror's Edge and Remember Me), and it's nice to see these big companies incorporating more of the genre into their games and twisting them in a fresh and inventive way. However, I've always loved indie games the most: games like Transistor and Neotokyo have been really great sources of inspiration for me.
Transistor is a really well-known indie game, having won a ton of international rewards for its artwork and soundtrack. Its art style is just amazingly beautiful and the world and environment completely shows the crazy amount of effort that was put into it. One of my favourite games of all time~
Neotokyo is in my opinion one of the most underrated mods of all time. A free mod for HL2, the game is similar to a cyberpunk-version of Counterstrike, but a lot more emphasis is placed on positioning and strategic thinking rather than reflexes and map control. There's cloaking, cyber goggles, and a really nice futuristic metropolis setting that is very pretty and well-thought out considering how small the team was and the fact that it was a hobby project. It also has an incredible soundtrack that's sadly not used in-game, but conveys the cyberpunk theme very well and is available to download for free! I'm not very good at first-person shooters, especially considering the massive amount of team coordination needed in Neotokyo, but it's free and the file size isn't very big so definitely worth checking out if only to explore the maps.
