Something which is found in the game environment that bestows a positive benefit. Different from inventory items in that their effect is usually instant. Often inexplicably drops from the corpses of fallen enemies, and is found in unlikely places and breakable objects, or the odd [[InexplicableTreasureChests treasure chests]].
A feature found in many games is the cycling power-up, an item that cycles between two or more different power-ups (either on its own or when you shoot it), forcing the player to decide on which one is most important to them. Depending on how fast it cycles, it also tests the player's timing. These are common in space shooters.
* [[HealThyself Health Recovery]]
** Medkit with red cross (ironically, UsefulNotes/TheRedCross doesn't like this, since the red cross is a symbol regulated by international laws with a very specific meaning; the actual first aid symbol should be a white cross on green).
*** More recent works have started using glowing green crosses instead.
** [[HeartsAreHealth Heart]]
** HealingPotion, usually a crystal vial with neon red, green or blue liquid inside.
** Wrench (in vehicle games)
** Glowing orbs of LifeEnergy
** [[HyperactiveMetabolism Food]]
* Enhanced Abilities
** [[TransformationTrinket Transformation items]]
** [[CrateExpectations Military shipping crate]]
** Another gun like your current one
** Loose clips/magazines, rockets, arrows, etc
** [[FollowTheMoney Gold coins]]
** Stacks of bills
** Gems or jewelry
** Sacks marked with a dollar sign
** Gold bars, ingots, or bullion
** Floating dollar sign
** Icon that reads "1UP"
** Icon or doll of the player character('s head)
** Heart (if not used for health recovery)
** [[LawOfOneHundred Every 100 of a common item]]
A common trait among powerups is that you often don't need to do anything other than touch it to gain its benefit. Fly your fighter into the floating container of radioactive materials (''VideoGame/RaptorCallOfTheShadows''), send the chopper into a bomb pod (''VideoGame/TwinCobra''), and they just get installed or deposited instantly. Usually an [[AcceptableBreaksFromReality Acceptable Break From Reality]] since no-one really wants to fly out of a dogfight to spend some quality time in a hangar with a wrench installing a missile pod--and dealing with the damage from ramming it into the fuselage to catch it at mach 50. When a common powerup is used to increase the player's weapon level or something, collecting more of it after reaching maximum level often results in ScoringPoints instead.
Sometimes comes with its own PowerUpMotif-- usually when it's a TimedPowerUp-- as well as the StandardPowerupPose.
Compare StatusBuff, PowerUpMagnet. If the powerup isn't very useful, see PowerUpLetDown. If a level doesn't contain a powerup, it is a DroughtLevelOfDoom. Contrast PoisonMushroom, a [[InvertedTrope power-down]].
