Health pickups are items that can be collected in the various maps during gameplay. They restore a set amount of the user's health when picked up and automatically regenerate after ten seconds. There are three different types of health pickups (small, medium, and large) that can be found with each restoring a different amount of hitpoints depending on the size of the pickup and the class you're currently playing.
A player can be healed by several different methods, including healing by friendly Medics. Since these pickups are a vital item in combat be sure to use them wisely; consider letting a teammate who has less health than you grab it, or especially a nearby Medic who may need it.
