Secondary meanings:
The axes of a two-dimensional Cartesian system divide the plane into four infinite regions, called quadrants, each bounded by two half-axes.
These are often numbered from 1st to 4th and denoted by Roman numerals: I (where the signs of the two coordinates are (+,+)), II (−,+), III (−,−), and IV (+,−). When the axes are drawn according to the mathematical custom, the numbering goes counter-clockwise starting from the upper right ("northeast") quadrant.
The Quadrant Cycle Company was a company in Birmingham, England that was established in 1890 as a bicycle manufacturer. They advanced to make motorcycles from 1899 until their demise in 1928. They also made a tricar called Carette in 1899 and a small number of cars for about two years around 1906.

Soulstar is a pseudo 3D space shooter in a similar vein to Nintendo's Star Fox, released in 1994 for the Sega Mega-CD.
The game is a shoot 'em up viewed from a behind-the-ship 3D perspective incorporating scaling and rotating sprites style of graphical effect. Soulstar was amongst a handful of games developed by Core Design using this graphical style among Battlecorps, BC Racers and Thunderhawk. The game also features a CD quality orchestral soundtrack.
The Myrkoids, an alien species with a unified mind, descend upon unsuspecting star systems, sucking them dry and draining every planet of its internal energies. Following the destruction of his home system, Bryk Hammelt, the last of a noble race of warriors known as the Cryo-commandos, sets out in his starship, the Treaghon, to hunt down the Myrkoids.
Gameplay is based around three vehicle types, that the player space combat vehicle transforms into. The first mode is an on rails shoot 'em up, similar to the Star Fox and Space Harrier. This mode involves flying a Strike Craft through space towards huge scaling sprites of a planet or space station and flying across a texture mapped planetscape. The second mode involves controlling a hovering Turbo Copter in 360 degrees of freedom, allowing the player to move freely across the map. The third mode uses a similar 360 degrees mode, but this time the player controls a mech Strike Walker.
