Twin Hawk

Twin Hawk is a 1989 vertically scrolling shooter video game developed by Toaplan and published by Taito for arcades. Taking place at the end of an alternative World War II setting, where general Giovanni and his army plots to take over the fictional country Gorongo, players assume the role of a wing commander from the Daisenpū squadron taking control of a Flying Fortress fighter aircraft (known as the A6M Zero) in an effort to overthrow the enemy.

Created by Yuichirō Nozawa, Twin Hawk was developed as a commission for Taito by most of the same team that previously worked on several projects at Toaplan and made use of the former's Taito X System board. The game was later ported to consoles including the Sega Mega Drive, PC Engine and PC Engine CD-ROM², with each one featuring several changes and additions compared to the original version.

Twin Hawk is a military-themed vertically scrolling shoot 'em up game reminiscent of Sky Shark, in which players assume the role of a wing commander from the Daisenpū squadron taking control of a Flying Fortress fighter aircraft (known as the A6M Zero Fighter) through multiple levels to defeat an assortment of military enemy forces like tanks, battleships, and artillery to overthrow general Giovanni and his army as the main objective. Like Tiger-Heli, there are no flying enemies in the game. The title initially appears to be a standard vertical scrolling shooter, with players controlling their craft over a constantly scrolling background and the scenery never stops moving. Enemies are shot down using the main shot that travels a max distance of the screen's height. Common to Toaplan arcade titles, there are various differences between the Japanese and western versions, such as Twin Hawk versions containing co-operative play.

A unique gameplay feature is the bomb mechanic in the form of a group of friendly planes; pressing the bomb button will call in six Flying Fortresses to surround and protect the player's plane and provide back-up fire. After taking enemy fire, the friendly planes perform a kamikaze attack against nearest enemies below but players can also lead them to perform kamikaze as well by pressing the bomb button once all planes are already in formation. Double tapping the bomb button activates a bomb capable of obliterating any enemy caught within its blast radius. There are also various types of items scattered through every level: 'P' icons to upgrade the player's main gun, extra helper/bomb stocks and 1UPs.

Depending on the settings in the arcade version, the title uses either a checkpoint system in which a downed single player will start off at the beginning of the checkpoint they managed to reach before dying, or a respawn system where their ship immediately starts at the location they died at. Getting hit by enemy fire results in losing a live, as well as a penalty of decreasing the ship's firepower and once all lives are lost, the game is over unless the players insert more credits into the arcade machine to continue playing. The game loops back to the first level after completing the last one as with previous titles from Toaplan, with each one increasing the difficulty and enemies fire denser bullet patterns.
