Game Description
Prometheus harkens back to the old arcade days and the game Qix. Your job is to claim sections of the board by enclosing it in a shape drawn by the diamond-shaped controller. While you do so, you must avoid the sparks and the collection of shifting, rotating lines that moves around the game screen.Sparks also appear if you claim your territories too slowly. Contacting either the sparks or the lines causes your controller to explode. Every level, you are told how much territory you need to claim to win. This number starts out at 55% and goes up a small increment with each level. You must get this number or higher to win that round.
Areas you claim are colored in, while free areas are black. This game has a high scores table.

Review: Overall
Like Qix on which it is based, Prometheus asks you to claim space on a screen, thereby boxing in the Qix or as they are called in this game, the firestix. You must claim a certain amount of the game screen and avoid a variety of monsters that will try to impede your quest.First are the sparks. Instead of being of one color, there are green, yellow, orange, red, and mutating sparks. The green ones can be destroyed. Just use your controller to surround them in an area you are claiming. The other colors cannot be destroyed, so you shouldn't even try. The orange sparks will follow you, and the red ones are especially quick and deadly. Mutating sparks can be killed when they are green, but not after they have shifted color.
In addition to the sparks and firestix, other items can appear on the playing field. Planets are worth additional points, and the object that looks like your controller is worth an extra life. Watches also appear and affect the movment of your controller or the playing field. They are also worth extra points.
Three games are available in this program. One is straight Prometheus, which plays just like Qix. Prometheus Pro adds more of the extra goodies and Prometheus and Atlas is a two-player game in which players can compete or aid each other.
Points are awarded for the amount of space you enclose and if you manage to enclose more space than you have to, you gain a large bonus of extra points, based on the difference between what was needed and what was attained.

Review: Enjoyment
Still very enjoyable. The appeal of this game is that is has not been done to death or given rise to a hundred clone games.~ Lisa Karen Savignano, All Game Guide
Review: Graphics
Through the graphics are fairly simple, they have withstood the test of time and appear minimalist.~ Lisa Karen Savignano, All Game Guide
Review: Sound
You'll never forget the sound of sparks on your tail or the fuse telling you to hurry.~ Lisa Karen Savignano, All Game Guide
Review: Replay Value
There is endless variation, and the enemies never seem to move the same way twice.~ Lisa Karen Savignano, All Game Guide
Review: Documentation
Describes the goodies, how to play and the three game variations.~ Lisa Karen Savignano, All Game Guide

Prometheus is an inner satellite of Saturn. It was discovered in 1980 (some time before October 25) from photos taken by the Voyager 1 probe, and was provisionally designated S/1980 S 27.[3]
In late 1985 it was officially named after Prometheus, a Titan in Greek mythology.[4] It is also designated Saturn XVI (16).[5] Pronunciation for Prometheus is 
/prɵˈmiːθiəs/, US dict: prō·mē′·thē·əs; Greek: Προμηθεύς.
This small moon is extremely elongated, measuring about 136 by 79 by 59 km. It has several ridges and valleys and a number of impact craters of about 20 km diameter are visible, but it is less cratered than nearby Pandora, Epimetheus and Janus. From its very low density and relatively high albedo, it seems likely that Prometheus is a very porous icy body. There is a lot of uncertainty in these values, however, and so this remains to be confirmed.

Interactions with F Ring and other moons
Prometheus acts as a shepherd satellite for the inner edge of Saturn's F Ring. Recent images from the Cassini probe show that the Promethean gravitational field creates kinks and knots in the F Ring as the moon 'steals' material from it. The orbit of Prometheus appears to be chaotic, as a consequence of a series of four 121:118 mean motion resonances with Pandora.[6] The most appreciable changes in their orbits occur approximately every 6.2 years,[1] when the periapsis of Pandora lines up with the apoapsis of Prometheus and the moons approach to within about 1400 km. Prometheus is itself a significant perturber of Atlas, with which it is in a 53:54 mean longitude resonance.[1]
