Performed 5 headshots in 5 seconds.
Walkthrough[]
If you're having trouble, make sure you purchase the accuracy and stability upgrades through the Arms Dealer when they become available. Close combat with large groups of enemy using an accurate pistol works best for this. Other tips would be turning aim assist to high or allowing a sentry to call in reinforcements. Reinforcements often charge at Lincoln in groups, making getting five within the time limit easier.
