Data Security Achievement
Hacked 23 Blacklist Laptops
Blacklist Laptops are another form of collectibles scattered throughout the campaign and COOP missions. Unlike Dead Drop flash drives, Laptops do not show up with the Paladin's Command & Control Tier 1 upgrade. You will need an additional $150,000 to purchase the Tier 2 upgrade for them to show on the HUD. Grimm will notify you when you are near your first Laptop on the first mission.
Approach each Laptop quietly, if you are engaged in combat it will self-destruct and you won't be able to hack it. If this happens, reload the checkpoint.
