Operation Black Mesa is a total remake of Half-Life: Opposing Force. Utilizing the Source engine, Tripmine Studios plans to recreate the Black Mesa Research Facility from the ground up, as seen by the protagonist, Adrian Shephard.


Planned Features
• As a total conversion mod, Operation Black Mesa aims to be composed custom content entirely.
• All original maps re-created and re-envisioned for better realism and gameplay.
• Some maps are enlarged / extended to create a more lengthy and immersive experience.
• Improved AI, making enemies smarter and combat more dynamic.
• More enemy encounters to keep the action fresh.
• Scripted scenes with all the original Opposing Force characters to help bring the story to life.
• Textures and models pushing the limits of the Source engine, to bring you as much artistic detail as possible.
• New voice acting, new sound assets and a new soundtrack.
• Multiplayer that will bring back the classic gameplay, but also many new features, maps and game modes!
• Guard Duty, a remake of Half-Life: Blue shift is also being developed as DLC for Operation: Black Mesa.

You are doing a great job I appreciate that really. But maybe I couldn't have a chance to try this masterpiece in my remaining life.
So, I'll absolutely recommend this to my grandson. Who knows if he could luckily have the chance.
Anyway I respect your effort.

There are unfortunate reasons people feel this way. Partly is because the project has been in development for almost 19 years, with it being restarted multiple times. Recently, the dev team was fractured, as a lead dev said some less than appropriate things, and was punished, causing a divide on the team. This has erased nearly 50% of work on the project, as those who left, took their work with them. Will the project ever be completed? It's possible, the dev team are still incredibly passionate, but at it's current rate, it is likely another OP4 remake project will be completed prior, which hopefully will not demoralize OBM's continued development. Overall, these are the factors that have led to lost faith in the project, though nasty comments should not be left, as they are unnecessary and frankly, cruel. Here's to a productive and drama free 2025 for these guys, despite everything, they show no signs of stopping.

I don't think it's 50%. This claim need proof, please.

Surprisingly polite and respectful. Certainly the last thing I expected in response. Still, I must disagree with the notion that these people have any good reason whatsoever to be negative and act like they're owed something as they have been.

These devs are people working for free to provide people with something awesome purely out of their own passion. There is absolutely no rational negative response to that. Period. They don't owe people anything just because they've taken this much time to make something for nothing in return. If these people are upset that the team had internal drama, then they should probably stop contributing further to the team's stress with their negativity. If these people want to play an Opposing Force remake so badly, then they should stop negatively contributing to the leading one in development. What these people are doing is stupid and insufferable, and I'll happily be the one to call it out. People are allowed to be unhappy and discontent, but if they're going to express that negativity out loud like stupid children without being even remotely close to having a good reason to do so, then they should keep their mouths shut.

Having babies in the back seat screaming and crying about how long the trip is isn't going to get the car to Disneyland any faster. All that does is prove that a spanking is in order.

Gee, I wonder where these negative people would go on their way to do just to prove a point... Oh, wait...
