Has gog.com plans to add this expansion pack to catalogue?
That would be nice..

I second this request.

Yep, for what it's worth, I third this request.

I'll request it if only to provide a solution for those folks who bought Dominators and are not able to make it function, like myself.

You guys should consider buying the game at Amazon.

http://www.amazon.com/dp/B003P2VIOW?tag=deals4dowcom-20

Right now it's $6.50, cheaper then when I got it.

copy&paste from your link:
Product Details
Downloading: Currently, this item is available only to customers located in the United States and who have a U.S. billing address.
Note: Gifting is not available for this item.

Sad Face.

Or is there workaround for this?

You could try Amazon UK: http://www.amazon.co.uk/Space-Rangers-Reboot-PC-DVD/dp/B002PU9SZG/ref=sr_1_1?ie=UTF8&qid=1313156585&sr=8-1

Costs a bit more, but it's there. Somewhere on that page is a link showing where the game may be shipped.

It's also selling on GamersGate right now. $10 US, which isn't bad, and in Australia it's down to $5. Mileage may vary, but it's worth $10 atleast.
