Hello, Can anyone provide some hints to get past the 4th level in Modern Combat Sandstorm. It's the level where you have to protect the palace. I've gotten the RPG and destroyed the tanks in the front and I've help Dozer on the left side and made it to Fox on the right, but then I always run out of time. Any suggestions. I'm going as fast as I can but I think I must be missing something. Thanks for any help you can offer. I've been stuck on this level forever.
