Alright just played.
Well done, overall.

This was clearly an ambitious mod, and you guys did well with presenting it.
The Good: I personally had no problem with the interface (it appears some did). The new artwork and comprehensiveness of it all. The music was great (I could hear some Zerg Starcraft in there, but no biggie, I always liked those tracks

) and fitting. Props on using the nightmare ships. Missions weren't too difficult, but not easy either. It's clearly been playtested. The cutscenes were very well done.
The Bad: (This might be a little long, but it's mostly pet peeves) First off, Shiva is a Hindu god, from Terran history. I was horribly taken aback when I saw a culture that existed thousands of years ago and galaxies away from even the most primitive of Terrans even coincidentally used the same name. It would've really added to the depth if the Shivans had been given a different name by the Ancients.
Other biggest problem I had with it is that there's not a whole lot of variation in the game. There's a single scanning mission in the beginning, and the rest of the campaign was either holding off waves of bombers or blowing up everything on the map. Lack of variety is just plain frustrating. It shows a lack of originality on the part of the designers (which I know you don't lack--you even paid enough attention to detail to
edit the rank structure--I noticed when I got promoted to Exarch

), and it makes for a very boring campaign in general. Throw in a little variety and this would be amazing.
All in all, great job.

If it weren't for the lack of mission variety and the Shivans still being called "Shivans", this would be the best campaign I've played in a long while.
