How to modify and adapt the 1994 post-apocalyptic driving game 'Quarantine' for integration with Doom engine

Sci-Fi, Dystopian & Simulation Game

I’m currently working on a project where I aim to take the classic 1994 game Quarantine and modify it to function with the Doom engine. If you’re unfamiliar, Quarantine is a unique driving game set in a dystopian world, focusing on a taxi driver who encounters bizarre passengers and risky scenarios.

I’m trying to figure out how to extract the game assets and decipher the original code structure to transfer the gameplay mechanics to Doom. One significant hurdle is grasping the vehicle physics and city navigation systems from the original game.

Has anyone attempted similar projects for retro game conversions? I’m keen on learning methods for analyzing outdated game files and extracting sprite data. Any suggestions for effective tools or techniques for reverse engineering would be greatly appreciated.

I’m particularly interested in how to transition from the original 2D sprite graphics to something that properly fits the format of the Doom engine.

That sounds like a crazy ambitious project. You might want to check out GZDoom for better sprite handling capabilities.

Never tried modding Quarantine but that game was absolutely bonkers. The whole driving mechanics thing seems like it would clash hard with Doom’s engine since it’s built for running around shooting stuff, not cruising in a cab.

I remember Quarantine being pretty wild back in the day. The whole taxi driving through a plague-infested city thing was so unique. What you’re talking about sounds incredibly complex though. The vehicle physics alone would be a nightmare since Doom wasn’t built for driving mechanics at all. You’d basically be rebuilding the entire movement system from scratch. Have you looked into any existing vehicle mods for Doom to see how they handled it?

You could try using Slade3 for extracting the sprite data from Quarantine’s files.
