Hey. Nah Wetwork is the one on the oil rig where it has the 2 slow-mo breaches
But that one your talking about, High Explosive, is REAL hard unless you do what i did and have a 2nd person help alott. I will try and find a link for a good stratergy guide on it if youd like? the way i did it was pretty easy and did it on veteran on the first attempt.
