History


Sega System 24 disk. published 31 years ago:

Gain Ground (c) 1988 Sega.

A one or two player shoot-em-up featuring single screen levels, in which players must rescue lost troops before making their way to the exit. Players can choose to play as any one of three different characters; each with their own unique weapons, strengths and weaknesses. Time is a factor in this game and all troops that do not enter the exit will be lost. All rescued troops will join the player's ranks as bonus players. The levels take players through fields, castles, forests, forts etc.

- TECHNICAL -

Runs on the Sega "System 24" hardware.

Players: 3
Control: 8-way joystick
Buttons: 2

- TRIVIA -

Gain Ground was released in November 1988 in Japan.

Cyber, one of the playable characters, was obviously influenced by the 1987 film RoboCop. In addition, the final boss for the final round bears a resemblance to ED-209 from RoboCop as well.
