Exit the Heat Loss Monitoring area and head up the ramp to the left to the Power to the People and Gatherer’s Garden machines. Finish upgrading the third weapon you chose to focus on then use the Adam you’ve collected from the Little Sisters to purchase the Electro Bolt 3 plasmid and, if possible, an extra tonic slot.
Little Sister Encounter
Big Daddy: Elite Bouncer
Ascend the staircase towards the Workshops entrance and continue a few paces to the north to find the third Little Sister. Take the necessary research photos then ready the Target Dummy plasmid and place a pair of dummies off to the side.
With the Target Dummies in place, you’re ready to start the attack. Hit the Elite Bouncer with a Heat-Seeking RPG or Frag Grenade, then switch to either Explosive Buck or, if you don’t have any of those left, equip the Chemical Thrower and torch it with Napalm! Add additional Target Dummies to the area to lure the Elite Bouncer off your scent, then reload and open fire again!
