Arcadia

Arcadia is an early 8-bit cartridge-based home video game console produced by Alta in Mariana. Introduced in 1978, it was the first and most successful Marianan video game console. Arcadia was developed from 1977, released in Europe in November 1978 and in Anglo-America in March 1979.

History
Development of the Arcadia began in the spring of 1977.

Arcadia
The original Arcadia was an all-black console. It featured only four buttons, an on/off switch, a reset button and two difficulty level selectors, with a choice of basic or professional. The controller was a 4-way joystick with a single red button (used for firing or jumping in games). The first Arcadia was last produced in October 1979, making it the rarest model.

Arcadia 80
The Arcadia 80 was an upgraded version introduced in December 1979. It had the same specifications as the original model, save for having a second controller and a new hot pink/white logo. The 80 was last produced in August 1981.

Arcadia 2
The Arcadia 2 was the final iteration of the Arcadia. It was introduced in March 1981. It featured Atari-style fake wood and saw the introduction of the action controller, an additional controller with not one but two buttons, for new games which allowed players to jump and shoot simultaneously. Final production of the 2 ended in February 1983.

Space Lasers
Space Lasers vertically oriented fixed shooter game, the most successful Arcadia game produced. Just over 1 million cartridges were sold. It was developed in Sierra's Silicon Valley. In Space Lasers, one is a spaceman wielding two laser guns. Three different objects go down the screen:


 * Spiders: the giant spiders are the slowest to come down the screen but many will appear, in higher levels often overwhelming players
 * Delta-wing fighter: quicker than spiders at coming down the screen
 * Space ship: The space ship is the fastest to reach the bottom of the screen, and in later levels fire their own lasers

As the player reaches each new level after 100-points, the game becomes harder, rotating from either more enemies appearing and them coming down at an even faster pace. After three lives have gone the player is defeated. Unlike Space Invaders, the "enemy does not come out as a long wall, but instead appear somewhat randomly.

Space Lasers was the third Arcadia game ever produced, sold for Christmas 1978. It was originally a black and white only game. In time for the release in Sierra and the United Commonwealth, Space Lasers was upgraded to color; a fixed color palette background was placed so as the enemies moved, their color would change. As of 2016 the official points record for Space Lasers was 10140.
