Operation Grid Assault Walkthrough in MW4 DMZ

Before you go

Threat assessment Critical; recommended gear: a 3-Plate Armor Vest and a Medkit. The mission screen lists Access the Network, Download Network Intel and Upload Kill Switch; the steps above are the objectives shown during the mission. The two code segments are in two different buildings in The Grid. You upload the code on a rooftop while enemies pour in, then one player climbs the radio tower to broadcast it. A Death Stalker helicopter commander can turn up on the roof.
