Health

All Survivors begin with 100 health. As they receive damage from Infected, their health decreases. Once their health is depleted, they fall to the ground and must be helped up by teammates. It is impossible for a wounded Survivor to permanently restore health back to 100. First aid kits do not heal past 99 health and pain pills only temporarily restore health back to 100. Movement speed is slowed at below 51 and is even slower when on critical health.

Health can be restored by first aid kits and pain pills, which can be found in first aid stations, safe rooms, Finales, and throughout the game.

First aid kits: First aid kits restore 80% of lost health in addition to resetting the number of times a Survivor can be incapacitated before dying.

Pain pills: Pain pills provide a temporary health boost equal to 50% of lost health. Temporary health is marked as vertical lines on the health meter (rather than a solid bar) and is reduced over time.

Health bar colors
The color of a Survivor's health bar changes depending on how much permanent health he or she has. At 100 to 51, the health bar is green. At 50-16, the health bar is yellow. At 15-1, the health bar is red. Since the color is based on how much permanent health the Survivor has, it is always red while incapacitated and after being revived but not healed.
