I grew up with the original x-com and terror from the deep, and regularly play them to this day. I personally didn't mind the FPS/third person shooter bit, and I think it even felt a lot more "under invasion" and scary than the x-com remakes.

So I actually liked it, but because it was so poorly made technically I never bothered to Finnish it. Maybe I'll force my way through it one day, because of the story and atmosphere, but it's frankly one of the worst pieces of gameplay I've ever tried.
