A Missile Zombie will come right after the first zombie and a Double-Cabin Aircraft Zombie appears very quickly. After that, the first wave will quickly arrive and the player will spot a Flying Gargantuar. Soon, more than three Flying Gargantuars will be on the screen at once.
The combination of Zombie Fighter, Missile Zombies, Double-Cabin Aircraft Zombie, Flying Gargantuars, and Imps will demolish all of the player's defenses and take out a lot of the player's ship's health, potentially causing the player to lose. At the final wave, the player's lawn will most likely be empty and only a small amount of health will remain in the player's ship.
