Rescue gives 80 ADAM; harvest gives 160
After defeating a Little Sister’s guardian, approach her and choose the displayed rescue or harvest interaction. Rescue grants 80 ADAM immediately; harvest grants 160. This is the original BioShock system. There is no adopt-and-gather sequence to complete before choosing, as there is in BioShock 2.
Collect Tenenbaum’s gift after three rescues
Every three rescues earns a gift left at a Gatherer’s Garden. Its 200 ADAM makes the basic comparison 440 ADAM from three rescues, including the gift, versus 480 from three harvests. Rescue gifts also include other rewards, so judging rescue only by the immediate 80 ADAM misses a substantial part of its value.
Prepare for the guardian before starting
A Big Daddy does not need to be attacked merely because it crosses your path. Check that it actually accompanies a Little Sister, then prepare supplies and a route through the room. Once the fight starts, keep obstacles between you and a charging Bouncer; standing in front of its drill gives you very little time to react.
Choose consistently if you want the rescue ending
Rescuing every Little Sister you encounter is the straightforward route to the positive rescue outcome. If that is your aim, keep manual saves before these choices so an accidental harvest is recoverable. The story treats how you handle the girls as meaningful, rather than as a temporary change to a combat statistic.
