I need a dark gritty future or cyberpunk book

Hello, chooms. My favorite genre of all time is cyberpunk but Ive read so many. Im looking for something maybe indie or underground. Here are some I've read:
Neuromancer and the sprawl trilogy by
Gibson
Snowcrash
Altered Carbon
When Gravity Fails
The Ware Tetrology
Gibsons Bridge trilogy
Hardwired
Gun, with Occasional Music
Do Androids Dream
Heroes Die

Basically im looking for that old school gritty future. Thanks
