@cschr, smoke counts as arty in the game, though not as dangerous they block sight of your guys and if it hits them directly they get gibbed, so its better count that as arty so you get warned
@yo2000, the negative xp is just what happens when u get promoted and still have xp left, for example, say you needed 100 xp to get promoted and you got 200 xp in your game, the points would be -100, so you will be promoted next game and the -100 xp will count toward your next promotion
lol, there was a flamer in front of my bunker, but it didnt shoot, my gunner shot it and it exploded, resulting in 4 troops on fire... awesome game... best ever.
