But what in the game but really upset me was that after (I guess) about 16 hours missions the game just in the middle of the mission hung, also a reboot from a savegame was not successful. It again and again locks up. And an increase in the level of difficulty is at Xcom really only that their own units suddenly just too stupid to be hit targets in front of the nose, but it is always taken himself out of the most unlikely corners. So at some point the game goes flutes and frustration is spreading ... Schade.
