I can't get past Hoth! I am playing on a PC, so having a friend come over and help is not an option.... Has anyone else played this and found it just painstakingly hard?? I breeeezed through the levels until this one, and it's on intermediate... I've even done two rounds of conquest and still can't beat the Hoth level in campaign mode... Any help would be appreciated, the walktrhoughs I have searched for only provide help for XBox and PS2 versions... Thanks again.
