FlameDuck: I think the Russian game you're thinking about is Silent Storm. It was a tactical turn based game, with completely destructable buildings. While a rifle shot could didn't have much effect (though you could shoot the enemy through wooden walls), a MG, grenade or bazooka could blow a hole in a wall you could use to get in an alternate way. Also, there were sometimes oildrums in the basements of this building that would blow up when shot, taking parts or the entire house with them. I would love to see a FPS that has completely destructable environments like that, where you can take out enemies hiding in the attic by blowing a hole in the floor below them. ;)
