You will get the Legacy Fortress Keycard from the Mercenary Stronghold Safe.

  1. You first have to raid a Mercenary Camp so that you can gain the Mercenary Stronghold keycard.
  2. These mercenary camps can be found across the map of Uzbekistan.
  3. After defeating the Mercenaries from the camp, you will gain the Mercenary Stronghold Keycard.
  4. Use it to get inside the Mercenary Stronghold, which differs from the Infested Stronghold.
  5. In the Mercenary Stronghold, you will find a safe containing the Legacy Fortress Keycard.
 Important: Buy Orange or Purple colored weapons from the buy station since it won’t be easy to kill off all of the mercenaries.

Head to the D2 part of the map, scan your keycard against the main gate and defeat the boss to complete the Legacy Fortress.

  • The Legacy Fortress is located toward the western side of the Popov Power, and its indication is a skull logo on the map. 
  • Once you reach the legacy fortress doors in MW3 and scan the keycard, you can step into the stronghold.
  • There will be tons of armored enemies, many Sentry Turrets, mines, and many other reinforcements.
  • I suggest you form a team and get inside because defeating all of the enemies won’t be easy. 
  • You have to deal with every enemy in the building to reach the final boss, Legacy.
  • Kill legacy, and then, the Legacy Fortress will be completed.
  • Players on X have acknowledged that the Legacy Fortress is one of the toughest challenges they have faced.

My Take On Completing The Legacy Fortress

The Legacy Fortress is one of the most difficult strongholds to complete in the zombie mode. There are so many enemies, like the main boss, boobie traps, attack helicopters, reinforcements, and turrets that you need to fight off. I have just a few tips that will help you beat most of these traps and attacks so you can complete The Legacy Fortress and get all the high-tier loot for yourself.

  1. Get some teammates to help you along this mission, especially to fight off the mercenaries. 
  2. You must at least have orange-colored weapons in your arsenal.
  3. Upgrade your weapons to Pack-A-Punch levels 1, 2, or 3 if you have the money.
  4. Have a teammate carrying a bazooka to blast off the helicopters. 
  5. If you have no friends and decide to play solo, then buy two or three self-revives before entering.
  6. Carry some good equipment and drill charges with you as well.
