Blast Furnace & Vulcan Raven

Enter through warehouse door NA-1 to access the facility's roaring Blast Furnace:

• Lower Sentry: Use the PSG-1 sniper rifle to drop the soldier patrolling the lower walkway before he raises an alarm.
• Molten Metal Ledge: Press your back against the western wall to shimmy across the narrow catwalk ledge over the vat of bubbling molten steel.
• Swinging Crane: A motorized crane sweeps back and forth. Duck down as it approaches to let it pass safely overhead, or fire a single Nikita missile to blow it off its tracks.

Pick off the guard on the far landing with the PSG-1, then enter the boiler control room: crawl through the low western vent to discover a secret cache containing Body Armor and Stinger missiles.

Make your way to the heavy freight elevator platform to descend toward the underground base:

• First Elevator Ambush: During the descent, three heavily armed Genome Soldiers rappel onto the platform. Circle the elevator perimeter while firing continuous FA-MAS rifle bursts.
• Exiting the elevator, equip Thermal Goggles to navigate around concealed landmines in the corridor.
• Step onto the second freight elevator: a murder of crows circles overhead in the darkness as Campbell radios in, revealing that Dr. Naomi Hunter has been placed under arrest by the Pentagon on suspicion of treason and espionage.

You arrive in a massive sub-zero refrigerated storage warehouse. At the far end, the giant shaman Vulcan Raven steps out, hefting a 20mm rotary aircraft autocannon.

Defeated, Raven surrenders the Level 7 Keycard and reveals that the Donald Anderson who died earlier was actually disguise specialist Decoy Octopus, before raven flocks consume his body.
