Health

Summary

The player in Halo: Combat Evolved has a finite amount of health that can only be restored by picking up Health Packs. Running completely out of health will result in death, but having lower health does not impede player actions. A player's health can only be reduced if his shields have failed. If the player's health is low the game plays a low heart-beat sound (so subtle it goes unnoticed by most players without large subwoofers).

In Halo 2, once the shields run out, the player also has a buffer of health. Unlike Halo: Combat Evolved, the health in Halo 2 regenerates after the shield. The amount of health left is not visible to the player.
