The main difficulty for this level are the huge waves of zombies, the big "Bot Swarm" ambushes, and the loss of Lawnmowers. Using powerful plants should get through this level easier. The Power Tiles are also beneficial, as they are placed far away from the zombies.
- 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 one.

Blover is very essential on this level. Use it when the Blastronaut Zombies appear and especially, when message "Bot Swarm!" appears to prevent having too many zombies to handle. For other strong zombies, use Primal Potato Mines, Cherry Bombs, Jalapenoes, and Hurrikale when necessary.
