I have been waiting for a long time for this to come out. Relive your experience with the original Half-Life in the source engine.
Free with HL2 installed on steam.
It was greened light on steam, soon to be released on it.
They have not finished the death match or Xen levels. Maybe we can host the death match servers!
Finally released. Download here:http://release.blackmesasource.com/
