Of course there was also a beta phase of Brood War. It was not as
as the history of StarCraft, but Brood War had to be tested too. There are
not many screenshots with interesting information, but these should give
you a little idea what Brood War beta was.
And I personally like the first screenshot. Look, 3 types of Archons!
I think it's a merge between a Dark and a High Templar.
