War of Aero - Project MEIOU — About this game

War of Aero: Project MEIOU flies through futuristic territory with weapons and support pods that can be adjusted during the battle. The ordinary shot handles the incoming enemies, while reversing the pods changes the direction they cover. A transformation trades movement speed for greater attack power, giving the player another response to the next defended passage. Weapon pickups include different projectile patterns rather than simply one fixed gun. Choosing the current formation while avoiding terrain and hostile fire is part of the scrolling route.
