Gain Ground (ゲイングランド) is a 1988 arcade game released for the Sega System 24 arcade platform. It is a top-down gun game with strategy elements, in which the player controls one of twenty playable characters who must defeat all the enemies on screen or bring every character that player currently has to the exit. It appears that two different arcade versions exist, one allowing up to 3 players while another supports only 2 players.
Called by developers as a "Algorithm Action Game", the core gameplay of Gain Ground is same in all versions. Players must either eliminate all enemies on the level or evacuate all members from the level by moving them to the "EXIT" (which in some cases can be very time consuming and unnecessary). Every character in the game has strenghts and weaknesses and only by using the right character for the right situation will help players finish the level. In addition to the enemies on the ground, some enemies are on the higher ground and can only be defeated with a character who posseses a weapon capable of hitting them.
Each character has one regular and one special weapon. Besides that, the only difference between characters is the movement speed. Each character's primary weapon can be fired with the primary button ( for Mega Drive, for Master System) and the special weapon can be fired with the special button (/ for Mega Drive, for Master System).
Each character has only one life and a single hit is enought to defeat them. When defeated, a small symbol of the character remains in the battlefield. That character can be rescued the same way of recruiting them: taking them to the "EXIT". If the character saving the downed character also killed, the previously defeated character will disappear.
Each "Era" is divided into ten levels. At the final level of an Era, players will face against a boss.

History
Gain Ground was ported to the Sega Master System and Sega Mega Drive in 1990 and 1991 respectively. The Mega Drive version received an exclusive 4th round called "Present Age", while the Master System version recieved its own exclusive last round "The Final Era". The game was also brought to the Super CD-ROM² in the form of Gain Ground SX. Both the Master System and Mega Drive versions allow up to 2 players cooperative gameplay; the Super CD-ROM² version is 1 player only.
The Arcade, Mega Drive and Super CD-ROM² versions are more or less the same game, except the Super CD-ROM² version has re-arranged Red Book audio.
Turbo Technologies, Inc. demonstrated a North American release of the Super CD-ROM² version at Winter CES 1993, but this release was cancelled for unknown reasons.
The Master System version differs significantly from the regular versions, with different characters portraits, slightly different character abilities (some characters are removed and some abilities are combined) and somewhat different level designs. Original versions feature more western-style character art while the Master System version's art is closer to an anime-style. Another interesting feature of the Master System version is that Player 1 uses male characters while Player 2 uses female characters. Besides the different portraits, there are no differences between male and female characters.
