Sky Destroyer

The player is about to destroy a submarine.

In Sky Destroyer, the player controls a plane, equipped with machine guns and torpedoes and ammunition is unlimited.

The color of the sky changes according to the time of the day (afternoon, evening, night). F6F Hellcats (F4U Corsairs in the Arcade Version) are common enemy fighter planes the player will encounter. Occasionally, the player would run into a B-24 bomber and has to shoot each of its four engines before the B-24 flies away. Sometimes when player has shot down a number of B-24s, they would encounter a falling satellite across the screen. A high number of points would be rewarded if the satellite gets destroyed. There are bonus stages in this game.

Enemy resistance comes not only from the air, but from land and sea as well. Sometimes, an American naval destroyer or submarine would try to down the player's plane with anti-aircraft fire. Aircraft carriers can sometimes be seen in the distant horizon (but can still be sunk with torpedoes). At the end of a stage, the player faces a mobile shore battery on an island. This battery must be destroyed in order to complete the mission. If the player is hit even just once by enemy fire, his plane crashes and he loses one life point.[2] The game is over when all life points are used up.

A hacked version of this game made by Inventor is known as Sky Invader. The differences between the original and the hacked version are:

• Different title screen.
• Different music.
• Different planes (both the player's and the enemies are modified).
• The sky is pink.
• The water color is different.
• The player starts with nine airplanes instead of three.
• The stages are called "WAR".

In Japan, Game Machine listed Sky Destroyer on their December 15, 1985 issue as being the third most-successful table arcade unit of the month.[3]
