Black Mesa - the Source-powered, modder-made re-imagining of Half-Life 1 - will be released 14th September.
Project Leader Carlos Montrero announced the news on the Black Mesa forum.
"On September 14th, you will see the first release of Black Mesa!" he wrote. "This will include our re-envisioning of Half-Life all the way up to Lambda Core. We believe this is a great way to provide a complete-feeling 8-10 hour experience with a solid ending, make our fans happy and help us make the best overall game possible."
"We are still working hard on Xen and BMDM, but instead of making you wait we are giving you Black Mesa as soon as it's ready! We're doing our best to help bring the immense vision of this project into reality, and we are very excited for what the future brings!"
