As the Airship

 * As the blimps don't have any guns on their front, simply targeting your target won't make your bullets hit it.
 * So, targeting beyond your target will make the blimps directly hit the target.
 * Because the blimps themselves have higher health/damage and speed, the strategy will work well.
 * Also try to keep the blimps invisible until some enemies come, and surprise the enemy.

Against the Airship

 * Beware of the invisible blimps. If you see the Airship itself, there may be some invisible blimps.
 * As itself is always visible, it's a good idea killing it before it move the blimps.
