The relatively low amount of zombies in this level, along with the fact that Lost Pilot Zombies and their destructive ambushes are not present make it fairly easy to complete.
Imp Porters appear from the very beginning of the level, and the small distance between them and the Gold Tiles makes it unlikely that the player will not face tents from the early start. However, Imp Porters do not pose a huge threat even if using an inefficient strategy.
Lava Guava is particularly good at dealing with Imp Porters even before they can set up their tent. Ghost Pepper can be used if the player has not purchased the earlier plant. Alternatively, Cherry Bomb also works fine.
The familiar pair of Excavator Zombie and Parasol Zombie appear through the second part of Lost City just as much as in the first one. Any strategies that worked before will be fine now. Red Stinger and A.K.E.E. keep true to the theme of the world, but any pair of straight-shooting and lobbed-shot plants will work.
Bug Zombies are rather unnoticeable throughout the level. Even picking up Blover is not necessary.
The Gold Tile in the eighth column can prove to be a minor problem, as it is relatively close to the right of the lawn, but this is only a minor problem.
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.
