[Heavy/power armour design?]

But that armor made me think of Mobile Infantry (Starship Troopers book not movie )

[Thoughts & Lessons from X-COM: Enemy Unknown (by Firaxis)]

I found the simplification system in EU to be a bit too far, the removal of TU's just felt like they were forcing me to go back to Kindergarten.

[X-COM: EU (2012) and what it could bring to Xenonauts]

Movement system: Not having to worry about time units and seeing exactly where you can move and how and the idea that you have to decide whether you want to take a shot or move some more made the gameplay much more enjoyable. This played very nicely with the Overwatch ability. Again, simple, but powerful.

I can never agree with this, the movement system is what got me to turn off Xcom EU (Although the rest of its toned down and simplified game play didn't help) and i hope never to see it in Xenonauts or any other tactical turn based ever again.

[[V16 Air Combat] Double combat]

I am still getting the double combat bug where i can hear the other combat going on behind the screen and it results in a crash to desktop.
