Super Secret

From Blood

A Super Secret is a feature in the game play of Blood. In each level, there are secret areas that usually contain power-ups or ammo. But in several levels there are Super Secrets, which are difficult to detect and difficult to reach. Some are nearly impossible to reach without cheating, and others and just plain undetectable unless the player is lucky. However, these super secrets often yield great rewards. For example, the Super Secret in E1M1: Cradle to Grave yields a Napalm Launcher, a weapon that otherwise cannot be found until three levels later.
