Shells (or Cartridges in Serious Sam Advance) are a type of ammunition in Serious Sam 1, Serious Sam 2, Serious Sam: Next Encounter, Serious Sam Advance, Serious Sam HD, Serious Sam: Double D and Serious Sam 3: BFE.
In every game that it has appeared in so far, shells appear as a white box filled with shotgun shells. They serve as ammo for all of the shotgun-type weapons in the Serious Sam games, such as the Double Barrel Coach Gun.
The amount of ammo in each box of shells depends on the game and (in some cases) the difficulty level. In Serious Sam 1, HD and Next Encounter, each box gives out 10 shells (20 in Tourist, Easy and Serious difficulties), while in Serious Sam 2 it gives the player 20 shells per box. Serious Sam 3 also has a special shell pickup shaped like the 12 Gauge Pump-Action Shotgun's magazine that gives 5 shells (10 in Tourist and 7 in Easy difficulties).
The below list shows how many of this item appears in each game.
