First aid kit

First aid kits (or "med kits") can be found randomly spawned throughout a campaign and in first aid stations. They take 5 seconds to use and restore 80% of the damage that survivor has taken based on their health not including temporary health. This healing will override temporary health. For example, a survivor with 30% health but has temporary health of 60% health due to pain pills, will be healed for 56% back up to 86% health, with no temporary health.

It is possible for first aid kits to spawn aside from safe rooms and the finales of campaigns, even in expert mode, though it is very rare.
