Probably the most famous powerup is the mushroom in Mario. It’s an item that comes out of a lootable (a breakable brick) that gives him a powerful but losable increase to his strength and size. A powerup can be any collected item, the effect usually temporary by time or until hit, that changes the behavior of the game. An objective could also bestow a powerup, but usually in this subgenre we’re using powerup to refer to something that is dropped by enemies or breakables and collected. We may refer to other “buffs” as a “temporary effect.” For our scaling, we include things like magnets that gather XP up powerups.
