Health

All Survivors begin with 100 health. As they receive damage from Infected, their health decreases. When a survivor's health is below 40, they begin limping and their movement speed is decreased. As their health level continues to drop, their limp increases in severity and their speed continues to decrease. By the time they reach 1 health point, their limp is extreme and their movement rate is significantly reduced. Once their health is depleted, they fall to the ground and must be helped up by teammates.

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. It is impossible for a wounded Survivor to permanently restore health back to 100 since first aid kits and pain pills cannot heal past 99 health.


 * First-aid kits : Restores 80% of a survivors fixed health. Also resets the number of times a Survivor can be incapacitated before dying. To heal yourself or someone else it takes exactly five seconds.
 * Pain pills : Provides a temporary health boost equal to 50 lost health. Temporary health is represented by vertical lines on the health meter rather than a solid bar, and decreases over time. Pills heal instantly which is a big advantage when under attack

Health bar color
The color of a Survivor's health bar depends on their amount of fixed health. Thus, a Survivor who has not been healed with a first aid kit since being incapacitated would always have a red health bar.

Death

 * Unlike most other games, Survivors get knocked down when their health falls to 0%. The incapacitated teammates can only shoot with their pistols and must be helped up by a teammate to continue.
 * Downed Survivors have 300% temporary health. When this gets to 0%, the Survivor dies.
 * Survivors can only be knocked down to the ground twice. The third time a Survivor's health drops to 0%, they die.
 * First aid kits reset the knock down counter, pain pills do not.
 * Dead Survivors will respawn if they are found in the Rescue Closets further in the level, or if the rest of the team completes the map.
 * Dead Survivors appear in rescue closets about 60 seconds after the Survivor dies.

Health Management

 * Never use first aid kits if you have green health unless there are spare kits available and your teammates don't need to heal more than you do.
 * Heal teammates. Do not hog the first aid kits; if one Survivor dies, that's one less gun in a panic situation.
 * If all your other teammates die because you are too greedy to heal them, suddenly you're by yourself on the ground, with a Hunter tearing you to pieces and nobody to help you.
 * If you are in a Safe Room with first aid kits and you have one yourself, use it to heal yourself, then take one on the table, as that is better than leaving it. Don't take more than one kit, though, unless another Survivor doesn't need one.
 * On expert difficulty, first aid kits almost never spawn outside of safe rooms and campaign finales. Save the kits until a person's second knock down, or until the team reaches a safe room where they can, hopefully, manage health pack distribution.
 * Pain pills are great in a pinch. If a Tank comes by or you get vomited on and have too little health to get away, take the pills.
 * If you feel that it isn't the right time to heal your teammate with a med kit, give them some pills instead. This should help them move along possibly to a point where more health items are located.
 * Ask for healing. If a person says no and can't give a good reason why, he/she may not be the best person for your team.
