i have a couple groups of guys in trenches or trees, and without fail the arty hits with 100% accuracy. and i dont have enough tp to get an engineer to build bunkers. i did at one point, and then as i was building it, the arty blew my engineer up. TT_TT
See previous 2 comments, and the in-game level up, increase range, attack, etc. dont seem to do anything. :( and if they do, its not reflected in the top right box when you click on a monster.
my square is 10 by 10, and i still have only one of the four things required for the BF badge. can you increase the frequency of the things a little more? I've had the spawn carrier three or four times, without so much as a trace of the other ones.
i think there is a glitch. when you skip levels to get to the one you left off on, and afterwards get a badge, you have to flip back a level for the accomplishment to register.
