 In video games, the combo short for combination is a set of actions performed in sequence, usually with strict timing limitations, that yield the 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 and ups, and sports games. Those are commonly used as an essential gameplay element, but can also serve as a high score or attack-powered 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.1 in some cases, each additional hit has an increasing negative modifier. In order to balance gameplay, it is shown in Capcom's Street Fighter ID series.2.
