Medium Health is a medium-strength health item in the Serious Sam games. In every game it appears, it gives the player 25 health points.
Its looks are different depending on the game. In Serious Sam 1, Serious Sam HD, Serious Sam: Next Encounter' and Serious Sam: Double D, it is a floating vial of green liquid. In Serious Sam 2, it is a floating red cross with a semi-transparent white circle surrounding it. In Serious Sam 3: BFE, it is a pack with a grey camouflage pattern and a red cross on its upper side. In Serious Sam Advance, it is a vial of blue liquid.
Medium Health is one of the most common healing items found throughout the games. It provides enough health that the player can withstand an extra hit or two, depending on how much armor the player has and the difficulty level, which is useful without overpowering the player. The only exception in Serious Sam 3: BFE, where it starts becoming common after the player leaves Cairo.
Medium Health occasionally appears in secrets, usually with more than one in them.
