Health cases appear as a rectangle with some edges cut off. On the bottom of the case is a small circle, a handle on the top of the case. The middle of the case is light green, with a + sign.
Health cases are rarely encountered in Toxic II. When encountered, they are found in places the Hazmat Hero will most likely come upon at low health. They restore one bar of health to his health meter, equal to one fourth of his maximum health.
