Here's that noir thriller built in the original Half-Life engine you asked for

There's been a surprisingly strong run of Half-Life total conversions of late, by which I mean there have been two of them. November brought us Diffusion, a massively ambitious sci-fi adventure with some truly eye-popping environment design, especially considering the age of its tech. Yes, it featured some terrible AI generated text-to-speech. But its creator is working on fixing that and recently revealed some of the human cast for its English dub.

Now, the GoldSrc engine has been given a lick of black paint in the pulp noir thriller The Last Goodbye. Created by Half-Life mod team Guild of Inventors, The Last Goodbye puts you in the stiletto heels of Lucille, a gun-for-hire nicknamed The Banshee who takes on a job to assassinate the deadliest gangster in the City of Prava, a cigar-chomping criminal mastermind known as Bullseye. Between you and your target is an army of pipe-wielding, pistol toting goons desperate to wrap their lips around the barrel of your shotgun.
