I had never heard of it so I'm going to guess that even though this is quite old, many people on TL haven't either. It seems to be the trailer/preview for an upcoming European Half-Life fan movie. The production is excellent and the video itself is very well done.
Atmospheric post-apocalyptic sci-fi with a lot of mysteries and questions to be answered. This sort of thing is right up my alley.
He said there was a second video involving a young couple, but I haven't been able to find it. If you read this Dana, post the video!
Any Half-Life/Sci-fi fans who missed this, it's a must watch. The production is sick considering it isn't made by any sort of professional studio. If it isn't an outright half-life film, it's definitely an homage to half-life or perhaps set in the same universe with an alternate storyline. Very cool.
