Action video game

The action game is a video game genre that emphasizes physical challenges, including hand–eye coordination and reaction-time. The genre includes diverse subgenres such as fighting games, shooter games and platform games which are widely considered the most important action games, though multiplayer online battle arena and some real-time strategy games are also considered to be action games.

In an action game, the player typically controls the protagonist or avatar. The avatar must navigate a level, collecting objects, avoiding obstacles, and battling enemies with various attacks. At the end of a level or group of levels, the player must often defeat a boss enemy that is more challenging and often larger than other enemies. Enemy attacks and obstacles deplete the avatar's health and lives, and the player receives a Game over when they run out of lives. Alternatively, the player wins the game by finishing a sequence of levels. But some action games, usually arcade games, are unbeatable and have an indefinite number of levels; and the player's only goal is to maximize their score by collecting objects and defeating enemies.

The action genre includes any game where the player overcomes challenges by physical means such as precise aim and quick response times. Action games can sometimes incorporate other challenges such as races, puzzles, or collecting objects, but they are not central to the genre. Players may also encounter tactical and exploration challenges, but these games first-and-foremost require high reaction speed and good hand–eye coordination. The player is often under time pressure, and there is not enough time for complex strategic planning. In general, faster action games are more challenging. Action games may sometimes involve puzzle solving, but they are usually quite simple because the player is under immense time pressure.

Players advance through an action game by completing a series of levels. Levels are often grouped by theme, with similar graphics and enemies. Each level involves a variety of challenges, whether dancing in a dance game or shooting things in a shooter, which the player must overcome to win the game. Older games force players to restart a level after dying, although action games evolved to offer saved games and checkpoints to allow the player to restart partway through a level. Increasingly, though, some games allow for 'resurrection' or 'cloning' and the opportunity to regain lost items upon death for a certain sum of ingame currency, typically increasing exponentially the more times the player dies. The obstacles and enemies in a level do not usually vary between play sessions, allowing players to learn by trial and error. However, levels sometimes add an element of randomness, such as an enemy that randomly appears or that takes an unpredictable path.
