Gratia - Second Earth (ver 1.0, 92047-01 version) — About this game
Gratia: Second Earth gives its ship different weapons for enemies in the air and on the ground. Its sideways-scrolling view keeps the terrain visible across the scene, so ground targets can remain important while aircraft attack overhead. Ordinary fire covers the aerial fight, while the air-to-ground laser addresses the other layer. Learn to recognise which kind of target is approaching before committing to the wrong weapon. A clear line in the air does not mean that the ground beneath it has stopped presenting a threat.
