BioShock 2 (Remastered) DLC, The Protector Trials
(BioShock: The Collection, 2016)
Scoring a perfect A+ rating (955 ADAM) on the Pauper's Drop Market 1 trial.
Tips:
+ You are equipped with the Headhunter Gene Tonic. Go for headshots. I prefer to stick with the Rivet Gun, using Heavy Rivets.
+ Set Cyclone Traps as needed around the Little Sister.
+ Try tossing up Brute Splicers with a Cyclone Trap, and use the moment they are stunned on the ground to line up a headshot. This will deal massive damage to an enemy with a huge health pool.
