Galaxy Force — About this game
Galaxy Force sends your fighter through enemy fleets and twisting stronghold tunnels. Choose which of four planets to attack first, then watch the space ahead for ships, projectiles and obstacles. Machine guns fire forward while missiles reward waiting for the lock-on indicators. Both weapons have unlimited ammunition, but your protective shield weakens with damage. Surviving the open approach is only part of the mission: the tunnel demands careful steering to reach the enemy’s nerve center.
