Star Destroyer

Trò chơi cổ điển của thập niên 80.

The objective of Star Destroyer is to score as many points as possible by destroying enemy missiles and bases. The player controls the Starfighter, a ship that can move in eight directions and fires both forward and backward simultaneously. Throughout the game, the Starfighter stays affixed to the center of the screen as it moves. During each round, several green enemy bases — known as "base stars" — appear, all of which must be destroyed in order to advance to the next round. The number of bases increases with each round. Each base has six globe-like cannons arranged in a hexagon around a central core. To destroy a base, the player must either shoot the core or destroy all six cannons, the latter of which gives the player extra points. In later levels, cores begin defending themselves by opening and closing while launching missiles. A radar display on the right-hand side of the screen shows where enemies are located relative to the player. The game also features a color-coded alert system.

Additionally, the player must avoid or destroy stationary asteroids, mines, and a variety of enemy missiles and ships which attempt to collide with his or her ship. Enemy bases will also occasionally launch a squadron of ships in formation attacks — destroying the leader causes all remaining enemies to disperse, but destroying all enemies in a formation scores extra bonus points. A spy ship will also appear occasionally, which must be destroyed or the game's alert system will turn to red regardless of how long the player has taken. Throughout the game, a digitized voice alerts the player to various events, such as incoming enemies or an approaching spy ship.
