Blue Shift is definitely coming to the PC as a port from the Dreamcast. Almost seems sacrilegious doesn't it? But whatever, at least it's more Half-Life so stop complaining. Another 27 levels of one of the best games ever aren't bad no matter where they came from. But the fact that it was being bundled with the original Half-Life for the Dreamcast also means that, due to space, it needed to be much smaller than the other expansions. So all in all, Blue Shift will weigh in around a third of the size of the original game.
