All incoming enemy planes are protected by two exclusive shields: red and blue. You can only deal effective damage by switching bullets to match the enemy's shield color perfectly. Red shields require red bullets, blue shields require blue bullets - any color mismatch will render your attacks completely ineffective, preventing you from breaking through enemy defenses.
Every time you clear a round, the enemy's health will permanently increase by 20%, making each subsequent cycle more brutal and challenging. Free drag of fighter jets to move, automatic shooting, easy operation. Challenge your limits and fight against the constantly escalating difficulty.
Let's eliminate enemy planes together.
