''Gravitar'' is a color vector graphics arcade game released by Atari, Inc. in 1982. Using the same rotate-and-thrust controls as Asteroids, ''Gravitar'' was known for its difficulty.〔(【引用サイトリンク】url=http://www.atariprotos.com/2600/software/gravitar/gravitar.htm )〕 It was the first of over twenty games Mike Hally designed and produced for Atari, including ''Star Wars''. The main programmer was Rich Adam and the cabinet art was designed by Brad Chaboya. Over 5,427 cabinets were produced.〔http://www.andysarcade.de/gravitar.html〕 ==Gameplay== The player controls a small blue spacecraft. The game starts in a fictional solar system with several planets to explore. If the player moves his ship into a planet, he will be taken to a side-view landscape. Unlike many other shooting games, gravity plays a fair part in ''Gravitar'': the ship will be pulled slowly to the deadly star in the overworld, and downward in the side-view levels. The player has five buttons: two to rotate the ship left or right, one to shoot, one to activate the thruster, and one for both a tractor beam and force field. ''Gravitar'', ''Asteroids'', ''Asteroids Deluxe'' and ''Space Duel'' all used similar 5-button controlling system. In the side-view levels, the player has to destroy red bunkers that shoot constantly, and can also use the tractor beam to pick up blue fuel tanks. Once all of the bunkers are destroyed, the planet will blow up, and the player will earn a bonus. Once all planets are destroyed, the player will move onto another solar system. The player will lose a life if he crashes into the terrain or gets hit by an enemy's shot, and the game will end immediately if fuel runs out. ''Gravitar'' has 12 different planets. ''Red Planet'' is available in all 3 phases in the universe; it contains a reactor. Shooting the reactor core activates a link. Escaping the reactor successfully moves the player to the next phase of planets, awards bonus points and 7500 units of fuel. Reactor escape time reduces after each phase and eventually becomes virtually impossible to complete. After completing all 11 planets (or alternatively completing the reactor three times) the player enters the second universe and the gravity will reverse. Instead of dragging the ship towards the planet surface, the gravity pushes it away. In the third universe the landscape becomes invisible and the gravity is positive again. The final, fourth universe, has invisible landscape and reverse gravity. After completing the fourth universe the game starts over. However, the reactor escape time will never reset back to high levels again. The programmers thought that even the best players could never complete the most difficult planets on the invisible levels. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gravitar」の詳細全文を読む スポンサード リンク
