Abilities are a feature introduced in Battlefield Heroes. They boost player performance and are usually limited in duration, followed by a cooldown in which the ability remains inactive until the period is over. Abilities are class specific and may only be used once they are upgraded to level one.
Abilities can be upgraded with Hero Points on the abilities screen found in the main menu of the game, with level five being the maximum level for an ability. Upgrading improves the effectiveness, duration, and cool down period of an ability. Players can also undo Ability upgrades and instead use the hero points to upgrade other items.
