This guide is for Not One Inch, which requires you to complete a lockdown event in Gorod Krovi.
In order to get to the lockdown event, you must build the Dragon Control Module and ride the dragon to the Pack a Punch location.
If you haven't gotten it already, you will earn the
Taking Flight trophy along the way
Once you get into the Pack a Punch location, go to the top floor. You will see a crystal in a machine covered in Apothican symbols, holding
on it will begin the lockdown sequence.
BEFORE YOU DO THE LOCKDOWN SEQUENCE-Ensure you're properly equipped for this battle: Juggernogg, Quick Revive, any other perks you think you'll need.
-Pack-a-Punch your weapon, as you'll be unable to do it during the lockdown sequence.
-Have a Gobblegum on you that can help, like Undead Man Walking.
Once you activate the crystal, all of the windows will boarded up except for one side. You must now defend the building from enemies on that side. Zombies, Manglers and Valkyries will appear in high volume, so make sure you conserve ammo. When playing this I didn't get a single max ammo drop from any of the zombies.
Once you kill all the advancing enemies from the one side, the windows will board up and the opposite side will open. Rinse and repeat.
The last part is the hardest as every window opens and you are attacked from all sides.
Once all enemies are dead your trophy will eventually pop.
You could also use this opportunity to earn the trophy Fire Mission
After the lockdown event you earn the Dragon Strike controller by picking it up where you activated the crystal.
