When the Ghosts arrive at the submarine pen, an alarm sounds. There’s no need to be sneaky—the enemy already knows you’re here. The alarm is accompanied by a countdown timer, which gives you exactly 10 minutes to reach the base’s mainframe. If you’re late, the base will go on lockdown, preventing you from accessing the critical data on the weapons cache. Follow closely behind the Warhound as it advances along the walkway. You can access two weapon boxes and an ammo crate along the way if you want to change your weapons or stock up on ammo. For the fight ahead, assault rifles and LMGs are recommended. When the word “Contact” appears at the top of the HUD, switch to Magnetic view to spot the hostiles waiting around the next corner. Find some cover and engage the hostiles with your own firearms—don’t launch the Warhound’s mortar at this close range.
