Hi I've been playing the game for a couple of years now on and off. I've done the campaign on easiest setting. I play the weekly challenge on Bronze which I love. My question how do you beat the silver or even gold challenges? I usually beat Bronze by buying a cannon and using that as cover as I move around the map. But silver I don't have enough money or get enough money from capturing the bases to get a canon.

Whats a sure fire load out, or technique to get through Silver mode? Or maybe some get tips, thanks in advance.

By the way this isan excellent game.
