The Atomic Health is an item in Duke Nukem 3D and its ports.
The Atomic Health gives the player 50 health when picked up. Unlike other healing items, the Atomic Health will heal the player up to 200 health points; 100 points greater than the player’s default health. This makes picking up the Atomic Health always a good idea, because having up to 100 extra health points is always useful.
Because the Atomic Health is so useful, its usually hidden either in secret or hard to get to areas.
