What's so cool about the Amiga WC1 Demo? Like the DOS WC1 Demo, it's not actually a playable package - the program simply uses source files to show off various elements of the game. It's also based on a prerelease version of the game and sports some unique differences because of it. Check out a video of the demo in motion at Pix's Origin Adventures blog here.
There is no sound or gameplay but there is a little original spiel and some of the cutscenes. The only changes I noticed on here were that the pilots are a lot more friendly when running for their ships,the cockpit visor slides in from a jaunty angle and the landing screen showing the ship damage has a very different colour scheme.
I would imagine that this was an extremely early preview long before the game was playable. Ultimately, the decision was made to drop to 16 colours so that it would run on A500′s whereas this demo makes use of a larger palette and looks all the better for it.
