Space Invadersis a 1978 shoot 'em up arcade video game developed by Tomohiro Nishikado. It was manufactured and sold by Taito in Japan, and licensed to the Midway division of Bally for overseas distribution. Space Invaders was the first fixed shooter and set the template for the genre. The goal is to defeat wave after wave of descending aliens with a horizontally moving laser to earn as many points as possible.
Platform gameA platform game (often simplified as platformer and sometimes called a jump 'n' run game) is a sub-genre of action video games in which the core objective is to move the player character between points in an environment. Platform games are characterized by levels that consist of uneven terrain and suspended platforms of varying height 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, air dashing, gliding through the air, being shot from cannons, or bouncing from springboards or trampolines.
Video game graphicsA variety of computer graphic techniques have been used to display video game content throughout the history of video games. The predominance of individual techniques have evolved over time, primarily due to hardware advances and restrictions such as the processing power of central or graphics processing units. Text-based game Some of the earliest video games were text games or text-based games that used text characters instead of bitmapped or vector graphics.
Level (video games)In video games, a level (also referred to as a map, stage, or round in some older games) is any space available to the player during the course of completion of an objective. Video game levels generally have progressively increasing difficulty to appeal to players with different skill levels. Each level may present new concepts and challenges to keep a player's interest high. In games with linear progression, levels are areas of a larger world, such as Green Hill Zone. Games may also feature interconnected levels, representing locations.
Beat 'em upA beat 'em up (also known as brawler and, in some markets, beat 'em all) is a video game genre featuring hand-to-hand combat against a large number of opponents. Traditional beat 'em ups take place in scrolling, two-dimensional (2D) levels, while a number of modern games feature more open three-dimensional (3D) environments with yet larger numbers of enemies. The gameplay tends to follow arcade genre conventions, such as being simple to learn but difficult to master, and the combat system tends to be more highly developed than other side-scrolling action games.
Third-person shooterThird-person shooter (TPS) is a subgenre of 3D shooter games in which the gameplay consists primarily of shooting. It is closely related to first-person shooters, but with the player character visible on-screen during play. While 2D shoot 'em up games also employ a third-person perspective, the TPS genre is distinguished by having the game presented with the player's avatar as a primary focus of the camera's view. A third-person shooter is a game structured around shooting, and in which the player can see the avatar on-screen in a third-person view.
Amusement arcadeAn amusement arcade, also known as a video arcade, amusements, arcade, or penny arcade (an older term), is a venue where people play arcade games, including arcade video games, pinball machines, electro-mechanical games, redemption games, merchandisers (such as claw cranes), or coin-operated billiards or air hockey tables. In some countries, some types of arcades are also legally permitted to provide gambling machines such as slot machines or pachinko machines. Games are usually housed in cabinets.
Space flight simulation gameA space flight simulation is a genre of flight simulator video games that lets players experience space flight to varying degrees of realism. Common mechanics include space exploration, space trade and space combat. Some games in the genre aim to recreate a realistic portrayal of space flight, involving the calculation of orbits within a more complete physics simulation than pseudo space flight simulators. Others focus on gameplay rather than simulating space flight in all its facets.
Isometric video game graphicsIsometric video game graphics are graphics employed in video games and pixel art that use a parallel projection, but which angle the viewpoint to reveal facets of the environment that would otherwise not be visible from a top-down perspective or side view, thereby producing a three-dimensional (3D) effect. Despite the name, isometric computer graphics are not necessarily truly isometric—i.e., the x, y, and z axes are not necessarily oriented 120° to each other.
Defender (1981 video game)Defender is a horizontally scrolling shooter video game developed by Williams Electronics in 1980 and released for arcades in 1981. A side-scrolling shooter, the game is set on either an unnamed planet or city (depending on platform) where the player must defeat waves of invading aliens while protecting astronauts. Development was led by Eugene Jarvis, a pinball programmer at Williams; Defender was Jarvis' first video game project and drew inspiration from Space Invaders and Asteroids.
