In every game that it has appeared in so far, cannonballs appear as a small pile of four cannonballs. They serve as ammo for all variants of the SBC Cannon.
The amount of ammo in each box of cannonballs depends on the game and (in some cases) the difficulty level. In Serious Sam 1, HD and Next Encounter, each pile gives the player 4 cannonballs (8 on Tourist, Easy or Serious difficulty). Serious Sam 2 gives the player 8 cannonballs per pickup and Serious Sam Advance gives the player 5 cannonballs per pickup.
- The cannonball's model appears in Test 1 and Test 2, but it cannot be picked up in-game. Both Test cannonball models are the same as the final's.
- According to Rich Knuckles, Sam holds the cannonballs in his pockets.
The below list shows how many of this item appears in each game.
