Some games are played with "reloads" enabled, which means that the number of shots a player can fire, or the number of times a player can be deactivated, is limited by a "power level" the player has. Each player has a certain amount of power for their pack, which is used up slowly by shooting and used up more quickly by being deactivated. Once that power is used up, in order to resume play the player must go to a reload bay, which are walk-in areas around the arena which will resupply the player with power. The actual device that reloads the packs is a green, flashing device on the wall or roof of the reload bay. Shots and deactivations use up the same supply of energy, so if a player is continually deactivated, they will not only have a lower number of deactivations left until they must reload, they will also have a lower number of shots to use. After a player reloads there is a short delay before they are reactivated.
