Captain Skyhawk

Captain Skyhawk is a single player video game developed by Rare and released in 1990 by Milton Bradley Company for the Nintendo Entertainment System. It features music by acclaimed composer David Wise.

Story
The player takes a role of a fighter pilot working to repel an alien invasion. Aliens have invaded Earth, and have built four land bases. These bases are designed to drain Earth's energy and feed it to their mother space station. If the space station is allowed to obtain enough energy, it will destroy the Earth with a massive laser blast. The player must destroy the enemy bases, then go after the space station itself. Scientists, during the course of the game, are working on a top-secret Neutron Cannon. During several missions, the player must make supply drops to the scientists working underground. Sometimes, the aliens will have a scientist captive. Then the player must defeat the alien base and take the scientist to safety.

Gameplay
The game is very reminiscent of the classic, Zaxxon. The game features top-down scrolling overhead isometric graphics, including simulated 3D terrain. The terrain mimics the look of flight simulators available for the PC at the time. The game player is the pilot of the plane, code-named the F-14VTS (a fictional version of the F-14), and must avoid the mountainous terrain while annihilating aliens.

There are a total of nine missions in the game. The first seven have three objectives each while missions eight and nine have two objectives and one objective, respectively. Each level has multiple routes, some of which allow the player to bypass large gatherings of hostiles. The objectives vary across missions and include destroying an enemy base, dropping supplies, fighting aerial battles, picking up a scientist, and docking with a space station.

Weapons
The player can fire four types of weapons: Cannon, Phoenix Air Intercept Missiles, Maverick air-to-ground missiles, and Hawk bombs. The cannon is the only weapon with an unlimited supply. The rest of the weapons must be purchased between missions after docking with the space station. The purchases are made with credits obtained through the levels by destroying all aliens that are in a group.

Level design
Each main level in captain skyhawk is and isometric plane.After the boss of the stage is destroyed or the packages are delivered you move on to a rear facing 2D screen where the player must destroy the enemy ships to gain credits to buy weapons in the space station on the end of the levels. The last space station is replaced with the alien mother-ship.
