I just finished the included campaign. I have to say it was borderline unplayable on Medium. When I wasn't being instagibbed by the Hunters on the enemy, well, Hunters, I was being knocked kilometers away by the kinetic impact on the Astaroth/Scout weapons.
The second mission was nearly impossible due to difficulty. I had to cheat. The rapidity with which you die is mind-boggling and infuriating. Similarly with the third -- I just got frustrated with such rapid and unavoidable death whenever an enemy Hunter targeted me. The gameplay is broken.
My biggest problem, however, was with the characterization of the Shivans. They say 'hell'? They're cute and friendly to each other? They get bored on long patrols? I hope you're not planning to go this direction with any future development of the Shivan race, because otherwise, the Shivan comm portraits and transmission noises were quite polished.
I had only one problem with the techroom -- the 'shotgun' taking inspiration from an ancient Terran weapon. Pleeeease. The Shivans predate the Terrans by millennia and have doubtless explored such simple, obvious methods of attack. I hope you'll rethink that description!
I'm going to check out the three demo missions. I imagine they're probably better.
