 Items in shooter games are not as common as in other genres, however, they still play a major role in the gameplay.The most common items are the health pack, similar to a potion in RPGs, and the Ammunition pack, a generic box of ammo that will work with whatever gun the player character has equipped at that time.Sometimes, in games with large amounts of different weapons, there will also be specialized ammo packs, like napalm canisters or Rockets/Grenades for Rocket and Grenade Launchers, respectively.
