Health bonus

A health bonus (or health potion) is a powerup that appears as a small blue bottle containing a special potion or medicine. Picking one up increases the player's health by 1% up to a maximum of 200%.

Health bonuses are worth 2% in many ports, including the Sega 32X, PlayStation and Sega Saturn ports as well as Doom 64. The upper limit of 200% can be altered with DeHackEd.

Health bonuses are included in the items percentage displayed at the end of each level.

 * Pre-V1.2 versions of Doom capped the maximum health value at 199 units rather than 200.
 * In a beta of Doom, Demonic Daggers served as a health bonus - when the player picked them up, his health went up 1%.
 * In Doom RPG, the health bonus is called a health vial. It increases the player's health by 4 units.
