Charges Set Call of Duty: MW3 Guide
Last update: 11 May 2016
If you accomplished the first circuit with three stars that shouldn't be a problem. Use default weapon. First place the charge and when the doors blow up hit terrorists in slow motion (watch out for civilians). Then run through the doors on the left and in march shoot down three enemies and after that another four.
After that run to the doors place the charge and in slow motion eliminate another group of enemies.
Go downstairs, use knife to eliminate foes and when you are outside shoot another terrorists.
Move right, change weapon to a pistol and shoot down four enemies (two of the are on the bridge above) and start running toward finish line. During run eliminate the last two enemies.
