VALVe software originally had plans to port Half-Life: Opposing Force into the Source engine (announced at E3 2004) much like Half-Life: Source. However, seeing the results of Half-Life: Source, we decided to take the task into our own hands.
If we manage to get our game on Steam, it won’t only bring in the advantages in form of SteamWorks implementation, easy installation and automatic updates, but also will help to make the community around the game much bigger. That will bring many advantages, including populated servers in the multiplayer. While on Steam, the game would be available up to 50 milion customers using the Steam services!

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.

Alright, I have one question for you, guys. Are you going to hire voice actors from Black Mesa (Kevin Sisk, Mike Hillard, and Micahel Tsarouhas)?

Ok then thanks and also that’s kinda disappointed that operation black mesa (and black mesa) can’t come to game consoles for various reasons, honestly I understand about it and I believe it would be expensive to make it happen

1. soon(tm)
2. I think that's their plan, yeah.
3. Tripmine studios is not related to black mesa.
4. IDK
5. They haven't said anything about consoles, but crowbar collective couldn't bring black mesa to consoles for various reasons, and their is no reason to believe those factors are any different for O:BM and guard duty.
