In normal mode, the player has to stop the zombies from stealing 10 screws.
Difficulty
This level is somewhat hard. You have plants like Laser Beans and Snapdragons. While they may be powerful, Zombie Fighters can outspeed them before they can kill it.
Waves
The small number next to the zombie icon means that zombie will always appear in that lane, with 1 being the topmost lane and 5 being the bottommost lane.
In hard mode, the player has to stop the zombies from stealing 10 screws.
Difficulty
Despite being the last Air Raid level, there are two plants that make this one easier than the other three: Winter Melon and Horsebean. Those two alone can easily beat the level. The only zombie the player must worry is the speedy Zombie Fighter.

Start off by planting two Snow Peas on C1R1 and C2R5. Upgrade them to Winter Melons when you have enough sun.
Fill up the lawn with Horsebean, while they have a long recharge time, their firepower makes up for it. Also, avoid upgrading it to Citron, since Citrons can only target one zombie in one lane.
