In video games, a combo (short for combination) is a set of actions performed in sequence, usually with strict timing limitations, that yield a significant benefit or advantage. The term originates from fighting games where it is based upon the concept of a striking combination. It has been since applied more generally to a wide variety of genres, such as puzzle games, shoot 'em ups, and sports games. Combos are commonly used as an essential gameplay element, but can also serve as a high score or attack power modifier, or simply as a way to exhibit a flamboyant playing style.
In fighting games, combo specifically indicates a timed sequence of moves which produce a cohesive series of hits, each of which leaves the opponent unable or almost unable to block or otherwise avoid the following hits in the sequence.
