Not sure of what use this would serve.

There is no night vision so why this crazy switch?

location?
for real share it because i remember making this request from the devs.

You mean this one, the "secret light switch"?

It definitely do not serve any purpose, other than being a simple easter egg. It's just a fun little detail.

And just ignore XeonicDevil. She's just salty because she thinks she singlehandely wrote the whole game, and gets no credit for it.

HE.. and he wrote more than you can imagine.. this is one of them.

Why would you need or want to disable all street lights?

because sometimes you say funny stuff and a developer just.. does it for the meme's

like the Type-66 was my design and idea, alot of lil things were added when me and pond smith did cyberpunk as roleplay on WOC i think it was.. +-15 years ago.
it's when we wrote cyberpunk into a fps.

my words to him was FPS is the most immersive.
i then wrote a list of games and their mechanics.
to be used as a blue print for the future of cyberpunk.. i has no idea this dude was legit.

at the time i had no idea who mike was..

now here's a fact mike worked for the army in phycology and is a deep writer... brain dance.. ha.. yep pond smith can send your mind to a strange scary place.
i know i was there.. dog towns dlc is our baby... all the rules sent to the curb.
and i helped write it and was banned the moment they were done.
10 points for capitalism.
