Are there any walkthroughs (detailed as much as possible)? I am about to finish Shanty Town Escape mission and I got to huge wall (gates) and I've been shooting at enemies that appear from two small windows. I've killed them at least 50. Nothing happens. What am I supposed to do? Jump over? I can't. It's too hig. I heard that something must blow up and that a small opening is supposed to open in the gates. Nothing happens. Can anyone help?
