http://en.wikipedia.org/wiki/KhrushchyovkaThe most prominent feature of Soviet landscape, notorious for its paper-thick walls, stinky staircases and sewerage with sadistic disposition. They are everywhere, thousands of them, forming dusty concrete labyrinths for homo sovieticus to live in. Off the top of my head I can think of at least three reasons to have them in Il-2:
1. With just few different models of Khrushchyovka you can create entire modern cities and therefore simulate every possible combat scenario in Warsaw pact countries from the 60's to the present day.
2. This model is very easy to create. All you need is a box of appropriate proportions and a skin. I volunteer to draw one, unfortunately I know nothing about 3d modelling and class files.
3. Popularity of Il-2 and SAS may rise tremendously, as everyone who have ever experienced horrible life conditions in these houses is eager bomb the crap out of them.
Also there are some variations, such as Brezhnevka: Khrushchyovka on steroids, featuring several (usually 4) additional floors and waste disposal system that itself could be classified as a medium-sized humanitarian disaster.
A multitude of variants can be made (with different heights and color schemes) hence the simplicity of this model. My recommendations:
Model 1-335. The most numerous of them all, built from 1958 to 1966. Dimensions (approximate): length 35 m., height 15 m., depth 12 m. Sometimes has small pitched roof (can be ignored).
Model 11-49. One of the most common Brezhnevkas. Built from 1965 to 1984. 52x25x13 m. Usually has small elevator shaft extention at the top.
Model 111-121-8. You can find lots of them in rural areas and military bases. Built from 1970. 21x9x12 m.
It would be awesome to have all these models (I can paint several skins for each, therefore at least 6-7 different objects could be made). In the worst case only 1-335 will be enough.
