is a military-themed run and gun video game released by Taito for arcades in November 1982. It was one of the first overhead run and gun games, a precursor to many similarly-themed games of the mid-to-late 1980s. Front Line is controlled with a joystick, a single button, and a rotary dial that can be pushed in like a button. The single button is used to throw grenades and to enter and exit tanks, while the rotary dial aims and fires the player's gun. The game was created by Tetsuya Sasaki. It was a commercial success in Japan, where it was the seventh highest-grossing arcade game of 1982. However, it received a mixed critical and commercial reception in Western markets, with praise for its originality but criticism for its difficulty. The game's overhead run and gun formula preceded Capcom's Commando (1985) by several years. The SNK shooters TNK III (1985) and Ikari Warriors (1986) follow conventions established by Front Line, including the vertically scrolling levels, entering/exiting tanks, and not dying when an occupied tank is destroyed. Gameplay Playing as a lone soldier, the player's ultimate objective is to lob a hand grenade into the enemy's fort, first by fighting off infantry units and then battling tanks before finally reaching the opponent's compound. The player begins with two weapons: a pistol and grenades, with no ammo limit. Once the player has advanced far enough into enemy territory, there's a "tank warfare" stage in which the player can hijack a tank to fight off other enemy tanks. There are two types of tanks available: a light tank armed with a machine gun and a heavy tank armed with a cannon. The light tank is more nimble, but can be easily destroyed by the enemy. The heavy tank is slower, but can sustain one hit from a light tank; a second hit from a light tank will destroy it. A single shot from a heavy tank will destroy either type of tank. If a partially damaged tank is evacuated, the player can jump back in and resume its normal operation; however, with either type of tank, the player must exit the vehicle within a few seconds of being struck by a fatal shot. If the player does not exit a tank before it explodes, he loses a life. An extra life is awarded at 10,000 or 15,000, and none thereafter. The tank battle continues
