During the first game of Xenonauts I put the base in a place where is my home town (part of the Polish Baltic, near Gdansk), unfortunately, during the first battle with the aliens my screen freezed during hidden combat, I did not have any saves, so this base is gone. During this game I have a base near Nagasaki, unfortunately the game freezed (also hidden combat) again when the third UFO crashed, but i have still a save before third UFO. I need here quick save, i really dont remember about saveing...
I think placeing base, between china and russia, is very very suitable, because of profits from crashed UFO's
