another action genre involving combat, where the player character must fight many enemies at the same time. Beat 'em ups, like traditional fighting games, display player and enemy health in a bar, generally located at the top of the screen. However, beat 'em ups generally do not feature combat divided into separate "rounds". During the 1980s to 1990s, publications used the terms "fighting game" and "beat 'em up" interchangeably, along with other terms such as "martial arts simulation" (or more specific terms such as "judo simulator") and "punch-kick" games. Fighting games were still being called "beat 'em up" games in video game magazines up until the end of the 1990s. With hindsight, critics have argued that the two types of game gradually became dichotomous as they evolved, though the two terms may still be conflated. Sports-based combat games are games that feature boxing, mixed martial arts (MMA), or wrestling. Serious boxing games belong more to the sports game genre than the action game genre, as they aim for a more realistic model of boxing techniques, whereas moves in fighting games tend to be either highly exaggerated or outright fantastical models of Asian martial arts techniques. As such, boxing games, mixed martial arts games, and wrestling games are often described as distinct genres, without comparison to fighting games, and belong more in the sports game genre. Game design Fighting games involve combat between pairs of fighters using highly exaggerated martial arts moves. They typically revolve primarily around brawling or combat sport, though some variations feature weaponry. Games usually display on-screen fighters from a side view, and even 3D fighting games play largely within a 2D plane of motion. Games usually confine characters to moving left and right and jumping, although some games such as Fatal Fury: King of Fighters allow players to move between parallel planes of movement. Recent games tend to be rendered in three dimensions, making it easier for developers to add a greater number of animations, but otherwise play like those rendered in two dimensions. Features Aside from moving around a restricted space, fighting games limit the player's actions to different offensive and defensive maneuvers. Players must learn which attacks and defenses are effective against each other, either through trial and error or communication with other players outside of the game. Blocking is a basic technique that allows a player to defend against basic attacks. Some games feature
