Gotta say this is very similar to my opinion of the main game, albeit I'm less heated about it (haven't played the expansion yet).

This isn't really a tactics game, it moves too fast. It's reminds me more of some of the action games on my iPad. I'm still having fun and most of the missions (in the main game) are pretty easy, although a few are annoying.

But I'm amused when each mission gives a description of various detailed strategies you can use, as if we're playing X-Com. There's no tactics here, just clicking a lot.
