are working on bringing Blue Shift to Black Mesa – and it's just released Chapter 2.
Black Mesa: Blue Shift began development its first release in March this year – consisting of Blue Shift's first chapter, which is basically just its tram-style intro. Chapter 2: Insecurity doesn't add any combat but allows players to explore Black Mesa and meet several of the cast, including appearances by the G-Man and Gordon Freeman himself.
Anyone interested can the mod direct from ModDB or through Steam Workshop. It's free, of course, although you'll need a copy of Black Mesa first. Included in the update along with Chapter 2 is a load of fixes and improvements to Chapter 1: Living Quarters Outbound, including extending the intro's ending by "a few minutes".
The team has apparently kept most of the voices from the original game, although have redubbed a couple of key parts – most notably the larger guard Otis and the "totally unimportant female scientist". They do have a composer working on a new soundtrack, however, which they released a new track from too.
There are eight chapters in total in Half-Life: Blue Shift, so with chapters one and two completed in just a few months that means it should all be wrapped up by next year, correct? Perhaps, but while Blue Shift is undoubtedly a lot smaller than Half-Life or even fellow Gearbox expansion Opposing Force, the first two levels are basically interactive cutscenes – the real game starts with Chapter 3: Duty Calls.
Hopefully it won't take as long as Black Mesa anyway, which lapped Duke Nukem Forever's development time two years before it finally released.
