We've just uploaded the version with steam achievements, there is 12 in all. But not too hard to get 100%. This version also has more polish and bug fixes. Steam should download this for you automatically.
The next update will be game options, and the intro. This will most likely be the final version.
Any bugs/balancing issues let me know on the forums,
Thanks guys,
Paul
