The game's system is somewhere between air combat and army warfare. It's a lot like the old game I played as a kid, and we control fighters to destroy the enemy's army. We crossed the line of fire and shot down one enemy after another.

1.up to 2 big kinds of enemy air and land ;
2.up to 6 kinds of enemy air army;
3.up to 7 kinds of enemy land army;
4.up to 20 missions.
