ThankTanks

Any one out there figured out how to find a weakness other then hanging off the clif? I tried hit and run, hideing behind the rocks , below the hill and shooting them when they come over it. It seems that there are to many tanks to go one on one. I tried shooting there tracks , at the brain, ramming them and shooting them at the same time, but in the end they get me. I'm playing solo, seems everything is on there side. Please contact me at oldbaldyjp if anyone has come up with other weakness I haven't meantion. My address is oldbaldyjp@yahoo.com
