Physical Gene Tonics

EVE Link

An essential Tonic. Supplies you with EVE every time you replenish you health with a first aid kit. Get it from any Gatherer's Garden machine (Medical Pavilion) for just 20 Adam. EVE Link 2, which provides even more EVE per kit, can be found in the wild as you first enter Farmer's Market.

Hacker's Delight

Supplements your health every time you successfully hack a device. You'll find it in the Medical Pavilion area, inside the Eternal Flame crematorium - fire up the furnace then search the ashes. The two upgrades give you additional health. Hacker's Delight 2 can be made at U-Invent machines (Fort Frolic), while Hacker's Delight 3 is located in Point Prometheus, inside Failsafe Armored Escorts.

Extra Nutrition

You'll receive a small health boost when you eat. Get the standard Tonic from a Gatherer's Garden machine (Neptune's Bounty) for 20 Adam. For what it's worth, Extra Nutrition 2 can be found in the wild, inside Sinclair Spirits (Fort Frolic) - you need to use the switch behind the counter to access the secret stairs outside. Extra Nutrition 3 is given to you if you research Spider Splicers to Level 4.

Medical Expert

Gives you an additional health boost when you use first aid kits. You'll find the standard Tonic in Lower Wharf, Neptune's Bounty. The two upgrades are both found in the wild - the first in Fort Frolic (given to you by Sander Cohen) and the second in Doctor Suchong's Clinic in Apollo Square.

Security Evasion

Causes security devices to delay seeing you for a few seconds. It's found near to Waterfall Grotto, Arcadia. Security Evasion 2 increased the delay further and can be found in Lower Heat Loss Monitoring, Hephaestus. It's a useful Tonic to have later in the game when the security steps up a notch.

Bloodlust

You'll receive both health and EVE when you whack somebody with the Wrench, making this a very useful Tonic. It can be made at U-Invent machines (Fort Frolic).

Booze Hound

Instead of losing EVE when you drink alcohol, with Booze Hound you actually gain some. Like Bloodlust, you can mix this together at U-Invent machines (Fort Frolic), although the ingredients should really be used on something that's actually useful.

4
You fetch some sticks and I'll find the marshmallows.

Sportboost

Increases the speed at which you rush and attack with the Wrench. Given to you if you research Thuggish Splicers to Level 2, with the speedier Sportboost 2 rewarded when you reach Level 4.

Scrounger

Lets you search corpses again to find different stuff, which may be better or worse than your original find. To get it research Leadhead Splicers to Level 2.

Natural Camouflage

A fine, fine Tonic that allows you to blend into the background when you stand still, making you invisible to enemies and security systems. Research Houdini Splicers to Level 2 and it's yours.
