High Quality Content by WIKIPEDIA articles! In computer and video games, power-ups are objects that instantly benefit or add extra abilities to the game character as a game mechanic. This is in contrast to an item, which may or may not have a benefit and can be used at a time chosen by the player. Although often collected directly through touch, power-ups can sometimes only be gained by collecting several related items, such as the floating letters of the word `EXTEND` in Bubble Bobble. Well known examples of power-ups that have entered popular culture include the power pellets from Pac-Man (regarded as the first power-up) and the Super Mushroom from Super Mario Bros., which ranked first in UGO Networks` Top 11 Video Game Powerups.
