In Gears of War 2’s Dirty Little Secret one of the goals is “Carry the Explosive Charge to the Secure Door,” and its pretty straightfoward, but 2 tips might make it smoother. First, when you and Dom have the explosive charge walk straight forward, and make a slight adjustment to the right so you can walk into the small freight lift (looks like a rectanglar indentation in the walkway dead ahead). Stop on the freight lift asnd Marcus will have Jack activate the lift for you.
Next, don’t go back the way you exited (which was off to the right after you enter the building again) or you will run into the one person wide door and have to turn back around. Instead walk straight ahead toward a doorway that was previously sealed and Marcus will have Jack rip the door while you deal with some company. Go through the door and you should recognize where you are. Proceed down the hallway where you know the secured door is and you will be asked if you have proper access yet. Marcus will answer yes and you will get a cutscene.
