Action game in the context of "Level (computer and video games)"

Multiplayer online battle arena (MOBA) is a subgenre of strategy video games in which two teams of players compete on a structured battlefield, each controlling a single character with distinctive abilities that grow stronger as the match progresses. The objective is to destroy the enemy team's main structure while defending one's own. In some MOBA games, the objective can be defeating every player on the enemy team. Matches emphasize team coordination, tactical choices, and real-time combat. Players are assisted by computer-controlled units that periodically spawn in groups and march along set paths toward their enemy's base, which is heavily guarded by defensive structures. Players can influence these units by eliminating enemy waves or supporting their own, affecting lane control and map pressure. This type of multiplayer online video games originated as a subgenre of real-time strategy (RTS); however, most of the traditional RTS elements, such as building construction and unit production, were removed in favor of a more focused player-versus-player experience. The genre blends elements of real-time strategy, role-playing, and action games, combining strategic depth with individual character progression and fast-paced combat.

The first widely accepted game in the genre was Aeon of Strife (AoS), a fan-made custom map released in 2002 for StarCraft, in which four players each control a single powerful unit and, aided by weak computer-controlled units, compete against a stronger computer. Defense of the Ancients (DotA) was created in 2003 by the Warcraft III modding community for Warcraft III: Reign of Chaos and its expansion, The Frozen Throne, with a map based on AoS. DotA was one of the first major titles to establish the core mechanics of the MOBA genre, serving as a direct inspiration for later titles, and the first MOBA for which sponsored tournaments were held. It was followed by two spiritual successors, League of Legends (2009) and Heroes of Newerth (2010), a standalone sequel, Dota 2 (2013), and other games in the genre, including Smite (2014) and Heroes of the Storm (2015).

A first-person shooter (FPS) is a video game centered on gun fighting and other weapon-based combat seen from a first-person perspective, with the player experiencing the action directly through the eyes of the main character. This genre shares multiple common traits with other shooter games, and in turn falls under the action games category. Since the genre's inception, advanced 3D and pseudo-3D graphics have proven fundamental to allow a reasonable level of immersion in the game world, and this type of game helped pushing technology progressively further, challenging hardware developers worldwide to introduce numerous innovations in the field of graphics processing units. Multiplayer gaming has been an integral part of the experience and became even more prominent with the diffusion of internet connectivity in recent years.

Although earlier games predate it by 20 years, Wolfenstein 3D (1992) was the highest-profile archetype upon which most subsequent first-person shooters were based. One such game, considered the progenitor of the genre's mainstream acceptance and popularity, was Doom (1993), often cited as the most influential game in this category; for years, the term "Doom clone" was used to designate this type of game, due to Doom's enormous success. Another common name for the genre in its early days was "corridor shooter", since processing limitations of that era's computer hardware meant that most of the action had to take place in enclosed areas, such as corridors and small rooms.

A platformer (also called a platform game) is a subgenre of action game in which the core objective is to move the player character between points in an environment. Platform games are characterized by levels with uneven terrain and suspended platforms that require jumping and climbing to traverse. Other acrobatic maneuvers may factor into the gameplay, such as swinging from vines or grappling hooks, jumping off walls, gliding through the air, or bouncing from springboards or trampolines.

The genre started with the 1980 arcade video game Space Panic, which has ladders but not jumping. Donkey Kong, released in 1981, established a template for what were initially called "climbing games". Donkey Kong inspired many clones and games with similar elements, such as Miner 2049er (1982) and Kangaroo (1982), while the Sega arcade game Congo Bongo (1983) adds a third dimension via isometric graphics. Another popular game of that period, Pitfall! (1982), allows moving left and right through series of non-scrolling screens, expanding the play area. Nintendo's flagship Super Mario Bros. (1985) and the subsequent Super Mario series were the defining games for the genre, with horizontally scrolling levels and the player controlling a named character, Mario, which became Nintendo's mascot. The terms platform game and platformer gained traction in the late 1980s.

StarCraft is a military science fiction media franchise created by Chris Metzen and James Phinney and owned by Blizzard Entertainment. The series, set in the beginning of the 26th century, centers on a galactic struggle for dominance among four species—the adaptable and mobile Terrans, the ever-evolving insectoid Zerg, the powerful and enigmatic Protoss, and the godlike Xel'Naga creator race—in a distant part of the Milky Way galaxy known as the Koprulu Sector. The series debuted with the video game StarCraft in 1998. It has grown to include a number of other games as well as eight novelizations, two Amazing Stories articles, a board game and other licensed merchandise, such as collectible statues and toys.

Blizzard Entertainment began planning StarCraft in 1995 with a development team led by Metzen and Phinney. The game debuted at the 1996 Electronic Entertainment Expo and used a modified Warcraft II game engine. StarCraft also marked the creation of Blizzard Entertainment's film department; the game introduced high quality cinematics integral to the storyline of the series. Most of the original development team for StarCraft returned to work on the game's expansion pack, Brood War; that game's development began only shortly after StarCraft was released. In 2001, StarCraft: Ghost began development under Nihilistic Software. Unlike the previous real-time strategy games in the series, Ghost was to be a stealth-action game. After three years of development, work on the game was postponed in 2004. Development of a true RTS sequel, StarCraft II: Wings of Liberty, began in 2003; the game was announced in May 2007 and was released in July 2010. StarCraft II continued with the StarCraft II: Heart of the Swarm expansion, which was released in March 2013. The third and final StarCraft II installment, Legacy of the Void, was released in November 2015. In 2016, a single-player nine-mission pack, Nova Covert Ops, was released in form of DLC.

Rhythm game or rhythm action is a genre of music-themed action video game that challenges a player's sense of rhythm. Games in the genre typically focus on dance or the simulated performance of musical instruments, and require players to press buttons in a dictated sequence in time with music. Many rhythm games include multiplayer modes in which players compete for the highest score or cooperate as a simulated musical ensemble. Rhythm games often feature novel game controllers shaped like musical instruments such as guitars and drums to match notes while playing songs. Certain dance-based games require the player to physically dance on a mat, with pressure-sensitive pads acting as the input device.

The 1996 title PaRappa the Rapper has been deemed the first influential rhythm game, whose basic template formed the core of subsequent games in the genre. In 1997, Konami's Beatmania sparked an emergent market for rhythm games in Japan. The company's music division, Bemani, released a series of music-based games over the next several years. The most successful of these was the 1998 dance mat game Dance Dance Revolution, which was the only Bemani title to achieve large-scale success outside Japan, and would see numerous imitations of the game from other publishers.

An action role-playing game (often abbreviated action RPG or ARPG) is a video game genre that combines core elements from both the action game and role-playing game genres.
