Med Hypo

"Now I just gotta stop by the Thrifty Care to pick up a med hypo, just to be safe."

- Dieter Sonnekalb

During the early development of BioShock, the Med Hypo was originally a consumable item to replenish health. It's function works similar to the rewarding effects of a Physical Tonic. Instead of filling the health bar like a First Aid Kit, the Med Hypo gives a boost of at least 30% health, but with an additional process of slowly filling the player's health bar for at least 8 seconds.

In the Development Walkthrough video of BioShock, Hunting The Big Daddy, the Med Hypo only appears as a looted icon, rather than an actual item. However, the icon does indicate that it uses green fluid, much like the original green health bar. Although the Med Hypo was removed before the final development of BioShock, an Audio Diary, Big Night Out, mentions the existence of the Hypo.
