BioShock upgrade guide
Take control and evolve yourself.
Engineering Gene Tonics
Security Expert
Makes hacking devices easier by slowing down the liquid flow and removing troublesome tiles. Found in Twilight Fields, Medical Pavilion. You'll received Security Expert 2 if you research Security Bots to Level 2, although it's worth pointing out that if you reach Level 4 then all hacks automatically succeed anyway.
Speedy Hacker
Slows down the liquid flow speed when hacking. Get this from the Painless Dental clinic in the Medical Pavilion. If you really can't hack it then buy the improved Speedy Hacker 2 from Gatherer's Garden machines (Olympus Heights).
Shorten Alarms
Reduces the amount of time that alarms sound for. Found in the Neptune's Bounty area, on the top floor of Fighting McDonagh's - enter 7533 to unlock the door with the combination lock and then listen to the Audio Diary inside. Shorten Alarms 2 does exactly what you'd expect and can be found on the lowest floor of Geothermal Control, Hephaestus.
Focused Hacker
Reduces the number of Overload tiles when playing the hacking mini-game. Found inside ice at the entrance to Fontaine Fisheries, Neptune's Bounty. Focused Hacker 2, which removes even more Overload tiles, is located on the fourth floor of Hestia Chambers, Apollo Square.
Hacking Expert
As above, only this Tonic removes both an Overload and an Alarm tile. You'll find it as you enter the Research Labs in Arcadia. The upgrade removes two of each tile and can be bought from a Gatherer's Garden machine (Fort Frolic) for 50 Adam.
Alarm Expert
Another non-essential hacking tool. This one removes only Alarm tiles. Find it on the leftmost balcony inside Fleet Hall Theatre, Fort Frolic. Alarm Expert 2 is found later on inside Optimized Eugenics, Point Prometheus.
Clever Inventor
A must-have Tonic that reduces the quantity of each ingredient required to make stuff at U-Invent machines by one. And by hacking the machine you can reduce the quantity by one again. Make sure you grab this from Suchong's Apartment in Olympus Heights.
Prolific Inventor
For every item you create at the U-Invent machines you get double. Great for stocking up on rare and powerful ammo. You get this for rescuing 18 Little Sisters.
Safecracker
Like the Security Expert Tonic, only specifically for hacking safes and locks. Rescue six Little Sisters to receive this. The upgraded Safecracker 2 can be found in the lower room of the Educational Facility in Point Prometheus.
