Tried the alpha again for the first time in month and I must say it is looking pretty good.
But the first thing I did on my first ground mission was ducking behind an obstacle and the guy went to a layer behind the obstacle. He was facing the north-east direction. Only the sitting legs could be seen the rest hidden.
