Abstract of Game Story In the game 911 Space 2000 the player takes on the role of a rescue starship captain in the hostile environment of a distant star system His or her mission is to pilot a star ship to rescue free floating astronauts and clear the interplanetary danger posed by an asteroid storm Complicating matters is the limited air supply of the lost astronaut The game is a fast paced arcade style game with strategy elements After either succeeding or failing to rescue the astronaut and clearing the asteroid field the player will move to the next level where additional asteroids are added Game Play and Appearance Appearance of Play Area The game is a 2 Dimensional top down space simulation taking place on a large playing field consisting of a single screen Movement of the player within the visible playing screen area will be relative to the fixed background Once the player moves to the boundary of the screen they will wrap around to the other side in the fashion of many arcade games Appearance of Game Elements The appearance of the graphics will be sprites bitmaps displayed on a black background with a smattering of distant fixed stars The asteroids astronaut and even the player s torpedoes shots will move relative to a fixed central star Sizes in addition to distance will not be to scale and will instead be kept small This will be done to account for the size of the playing area as well as for playability reasons All of these bodies to be seen on the screen at any given time increasing the game pace and emphasizing the impression of a dynamic astrological system Game Play Physics The game will include basic physics velocity momentum and gravity This will affect the player s ship missiles asteroids and lost astronaut Michael D Baker Jr Page

in time For playability reasons the lost astronaut will have an amount of air proportional to the number of asteroids for any given level The greater the number of asteroids the more air the astronaut will have The player will have a limited number of missiles for use against asteroids at any given moment The level will be completed upon achieving the goals of picking up the astronaut and destroying all of the asteroids Should the player not rescue the astronaut in time the level will be complete when all of the asteroids are destroyed Game Scoring The player will receive a score for each asteroid destroyed which will be a fixed amount The player will receive a score for each astronaut rescued by passing over them although the value of the astronaut will increase with the level difficulty Should the player accidentally shoot the astronaut an easy thing when there are too many asteroids then the player will be penalized No bonus or penalty will be applied to the player score if the astronaut runs out of air This scoring system should encourage players to want to rescue the astronaut while taking care not to carelessly shoot everything that moves at the beginning of a level Game Progression The game repeats until the player quits the game by pressing the escape key ESC or by being destroyed Coming in contact with a star or asteroid can destroy the player s ship At the end of the game the player score will be displayed The strategy of the game will require the player to make use of the gravity physics and planetary motion in order to rescue the astronaut This will also apply to obstacle avoidance Development Specification The game is designed for minimal systems and should run on a Pentium 400 or better with DirectX7 0 Disk space needed is 3 Megabytes Ram needed is as per the Windows 95 98 operating systems although 64 Megabytes is recommended A sound card is also recommended but not required Michael D Baker Jr Page 5 1 14 2019 911 Space 2000 PRODUCT
