Hard Difficulty is the second hardest difficulty in the game. It has appeared in all Serious Sam titles.
You can Rocket Jump (except in SS2 and SS3), as self-damage is enabled.
Enemies are more numerous than in Normal Difficulty, and are stronger (in Serious Sam 3, the enemy amount increases usually by only a few though). There is also a health and armor degeneration system in TNE and Serious Sam Xbox, so that if your health or armor is above 100, it starts degeneratin slowly, by 1 point at short intervals. Self damage is also enabled.
Hard is best played by players with at least some experience in Serious Sam games, not just FPS games, and have quick reflexes as well as have memorized most enemy spawn locations, which will make it easier for them to survive.
