i have played a few of these now but I am disappointed that the medals do not work but not really worried about them. I found that it had a degree of difficulty involved in the obtaining of water and armour but that added to the realism. the art work was alright but it would have been better if there was slightly more o add to the theme. also I grew a moustache during the game?
pro tip* I found I gathered more water when I travelled. armour is lost easily so ramp up the attack and use medkits if it ever comes to that.
