B-Wings

B-Wings (Ｂウィング) is a vertically scrolling shooter first released as an arcade video game by Data East in 1984. A version was released in 1986 for the Family Computer. It was Data East's first home release for the console. The Family Computer version is notable for its inclusion in many unofficial Famiclone multicarts.

Gameplay
The game consists of 45 levels (30 in the Family Computer version), and no background story or plot is given. The player controls a robotic aircraft called the FX-1, and collects weapon power-up parts (called a "wing") to progress through the levels and ultimately destroy enemy bosses called "Gobunasu" at every end of the level. The game consists of two different top-view screen levels, where the player can press the second button to descend to the ground whenever they do not have a power-up. The player is unaffected by attacks from airborne units while they are playing on the ground level, but the ship is automatically brought back into the air after a certain period of time. The player can still be hit by attacks from ground units while they are on the ground level, and can also lose their ship by crashing into obstacles. The 8-way joystick controls the player's movements, and one button is used for shooting, and the other is used for descending to the ground (or un-equipping wings). The background image continues infinitely when the player scrolls in the horizontal directions.



The game was remade to the Family Computer in 1986, but many changes were made to power-ups, sound effects, enemy attack patterns, and enemy appearances, making the gameplay considerably different from the arcade version. New additional background music was also included, and it also became possible to rapid-fire shots. Several warps and hidden items were also added, along with an ending screen.

Weapons
Weapons can be equipped onto the player's ship by collecting power-ups that corresponds to certain weapons. Weapons come in the form of "wings" that attaches to the ship's sides and each has different abilities. The weapon can be ejected by pressing the secondary button before equipping a new one, and may also be damaged by enemy attack. Damaged weapons will disintegrate and eject automatically.

When the player has no weapon, the ship will simply shoot two small projectiles at the front:


 * Cannon: Fires 3 projectiles in rapid succession, providing a machine gun effect.
 * Wide: Fires 5 projectiles that spread wider as they travel across the screen. If one shot hits an enemy, all other shots automatically disappear and are fired again.
 * Multi: Fires 3 projectiles that changes direction between 4 different angles.
 * Van: Fires 6 projectiles (5 in the arcade version) that travels for an extremely short distance, forming a defensive barrier-like effect.
 * Side: Fires 7 projectiles, 3 each to the left and right and 1 forward.
 * Anti: Fires 4 projectiles, 2 forwards (only one in the arcade version) and 2 backwards, allowing it to attack enemies coming from behind.
 * Ground: Fires 2 projectiles to the ground platform to attack enemies below. Only appears in the original arcade version.
 * Jump: Fires 3 projectiles, with one that is able to jump over any obstacle and explode after traveling a certain distance. An enemy or obstacle will only be destroyed if this projectile explodes upon them.
 * Hammer: Fires 2 projectiles in rapid succession and comes equipped with a pair of rotating projectiles, shielding the ship from enemy attacks. Only available in the Famicom version.
 * Dyna: Fires a short-range beam that goes through any enemy without disappearing. Only available in the Famicom version.
 * Fire: Fires a jet of flames capable of penetrating enemies and bosses. Only available in the Famicom version.

Special weapons
In the Family Computer version, there are three additional weapons hidden in several levels, usually underneath obstacles:


 * Sterling-Silver: Fires green rings that behave similarly to the Dyna, and it has shield mechanism similar to the Hammer.
 * Aurora-Harrier: Fires four helical-shaped beams, each to every directions around the ship.
 * Oct-Blaster: Fires eight projectiles around the ship in all directions.

Items
In the Family Computer version, several items are scattered throughout the levels, usually hidden underneath certain obstacle structures or randomly flying around the screen. Certain items became useless when shot (in which it turns into an umbrella), while others will change its effect:


 * Voltage: Allows the player to store spare weapons, which can be used by pausing the game and pressing the "select" button. This can only be used once, but can be stocked up.
 * Comet: Teleports the player four levels ahead, skipping any bosses at the cost of extra points.
 * Random weapons can be found at intervals throughout a level, which is the most suitable weapon for a certain area. To obtain it, the attached flying pods must be destroyed to release the weapon.
 * Letters: A diamond-like object with a letter that changes randomly when shot. Each letter corresponds to a specific weapon when picked up.
 * Card Decks: Grants the player an extra life or additional protection for the ship.
