Critical Mass (1985 Video Game)
''Critical Mass'' (known as ''Power!'' in North America) is a video game developed by Simon Francis and published in 1985 by Durell Software for the Amstrad CPC, Commodore 64, and ZX Spectrum. Plot An anti-matter power station on an orbiting asteroid is used by the local star system for energy. The station has been taken over by hostile aliens who are threatening to overload the power system which will turn the reactor into a massive black hole and destroy not only the planetary system, but several nearby stars as well. The object of the game is to make it to the heavily defended power station and disable it before the reactor reaches critical mass and implodes.

Your Spectrum
''Your Sinclair'', or ''YS'' as it was commonly abbreviated, was a commercially published and printed British computer magazine for the Sinclair range of computers, mainly the ZX Spectrum. It was in circulation between 1984 and 1993. History The magazine was launched in January 1984 as ''Your Spectrum'' by Sportscene Specialist Press. (Sportscene would later be renamed to Dennis Publishing in April 1987.) Initially, it was published bimonthly, changing to monthly in June 1984. With the January 1986 issue, the title was relaunched as ''Your Sinclair'', with the intention of expanding coverage of the QL into the main magazine (previously, ''QL User'' had been a pull-out section within the magazine), and any future computers produced by Sinclair. However, the magazine remained focused almost entirely on the ZX Spectrum games scene. In 1990, the magazine was sold to Bath-based Future plc, and the April 1990 issue was the first to be published by the new company. That issue's news ...

Zzap!
''Zzap!64'' was a computer games magazine covering games on the Commodore International series of computers, especially the Commodore 64 (C64). It was published in the UK by Newsfield Publications Ltd and later by Europress Impact. The magazine launched in April, with the cover date May 1985, as the sister magazine to ''CRASH''. It focused on the C64 for much of its shelf life, but later incorporated Amiga game news and reviews. Like ''CRASH'' for the ZX Spectrum, it had a dedicated cult following amongst C64 owners and was well known for its irreverent sense of humour as well as its extensive, detailed coverage of the C64 scene. The magazine adopted an innovative review system that involved the use of the reviewers' faces, artistically rendered by in-house artists Oli Frey and Mark Kendrick, to express their reaction to the games. These eventually evolved into static cartoons as the magazine began catering for a younger market. By 1992, the magazine had changed so dramatically i ...

Action Video Game
An action game is a video game genre that emphasizes physical challenges, including hand–eye coordination and reaction-time. The genre includes a large variety of sub-genres, such as fighting games, beat 'em ups, shooter games, and platform games. Multiplayer online battle arena and some real-time strategy games are also considered action games. In an action game, the player typically controls a character often in the form of a protagonist or avatar. This player character must navigate a level, collecting objects, avoiding obstacles, and battling enemies with their natural skills as well as weapons and other tools at their disposal. At the end of a level or group of levels, the player must often defeat a boss enemy that is more challenging and often a major antagonist in the game's story. Enemy attacks and obstacles deplete the player character's health and lives, and the player receives a game over when they run out of lives. Alternatively, the player gets to the end of the g ...

Black Hole
A black hole is a region of spacetime where gravitation, gravity is so strong that nothing, including light or other Electromagnetic radiation, electromagnetic waves, has enough energy to escape it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary (topology), boundary of no escape is called the event horizon. Although it has a great effect on the fate and circumstances of an object crossing it, it has no locally detectable features according to general relativity. In many ways, a black hole acts like an ideal black body, as it reflects no light. Moreover, quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with thermal radiation, the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is of the order of billionths of a kelvin for stellar black holes, making it essentially impossible to observe directly. Obje ...
