Here's a really great opportunity for some high quality damage modelling. I hope the devs will implement the ability to display holes in the armor plating, and through these holes see the fire on the inside, etc. Also, furiously burning fires through hatches, and hatches popping open during secondary explosions, etc. Judging by the standard of the current IL2 BoX damage modeling for planes, I have high hopes.
It would be nice for the something along the way of the 3D interior qualities of IDDK's 'WWII Battle Tanks: T34 vs Tiger', and the overall physics of Graviteam's 'Steel Armor: Blaze of War'.
Really, really looking forward what the devs come up with!
