Okay, so I'm on the mission where you've got to go to this warehouse in Hong Kong and find this guy call Deviant1. I've come to a dead end. I made it through the docks and all that and I'm in the warehouse district after you walk through the small underground garage. I went through that 3 story building and cleaned it out and killed everyone. Now, back on the street, I've killed everyone and there's no place to go. There are two cars that are on fire blocking the road and I suspect that you have to go that way, but you can't even get close to the cars without burning to death. To make matters worsem, there seems to be an irrate civilian that I may have opened fire on by accident. Well, he's got an Uzi and shoots at me with great accuracy and I can't shoot him back because that kills me too. Okay, any advice guys? Let me know. Thanks.
If I remember correctly, you need to check out the banners and notice boards above street level. You can cross these from the 2nd or 3rd story of the building.
Hope this helps.
