If the idea of Hotline Miami style gunfighting set in Hong Kong sounds good, then let me introduce you to The Hong Kong Massacre.
The first release on Steam from developers VRESKI, The Hong Kong Massacre focuses on a former detective dodging, diving and blasting his way through various top-down levels.
There's a limited amount of bullet time available, and a ton of colour. It's heavily stylised: I'm sure shotgun pellets don't actually have a bright red glow, but bugger me it's a nice looking effect when shards of wood, blood and bodies are flying everywhere.
It's a singleplayer only game, according to the Steam listing. There's no release date, but the ESRB rating gives me hope that a release isn't too far away. Not that there isn't plenty of games to catch up on already, mind you.
