Re: Difficulty system messed up (Skill = -1)
yes, I'm in the car. Before I stopped playing last night I consistently managed to kill the first wave of enemies that come out of the building where the "gate controls" are located by throwing grenades out of the car at exactly the right time, so they explode in the doorway when the enemies spawn. So I live longer than 5 seconds. In my last attempt I then got shot by a guy halfway through the level with a shotgun... so I stopped playing :-).
As I said, if I quit and restart the game, the Skill and Challenge settings have different values. I guess what you're implying is that the stat screen updates only after 5 seconds of gameplay?
