Sky City - Day 18

In normal mode, the player has to beat the zombies at level 1.

Difficulty

This is a Special Delivery level that properly introduces the Arbiter-X. With low-health plants, as well as not having Spinnapples for protection against Zombie Fighters, the player must resort to using its offensive plants as bullet-fodder. Thunderstorms are also present, with that in mind, Ampthurium's ability is necessary for clearing the status brought from the thunderstorms. Also, always prepare a Lantern Cherry for Arbiter-X.

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 one.

Waves	Non-dynamic zombies	Ambush zombies	Note(s)
1		None
2	3	None
3		None
4		None	Thunderstorm!
5	3	None	First flag.
6	3	None	Thunderstorm! Carries 1x Plant Food.
7	3	None
8	4	None
9	1 5 4	None	Thunderstorm! Carries 1x Plant Food.
10	3 4	None	Final wave. Thunderstorm!

Strategies

• Start off by planting plants. If necessary, Rotobagas should to be placed at column 4 onwards.
• Use Saucer Squash to stun multiple zombies, preferably with Zombie Fighters.
• Lantern Cherries should obviously be planted at columns 6-9, where it is effective the most.

In hard mode, the player has to defeat leveled-up zombies.

Difficulty

Level 3-4 zombies make this level extremely hard. Multiple high-health zombies are present, and they are hard to defeat with level 1 plants. It's best if you upgrade your plants to level 4.

Strategies

• The plants you're using are probably at level 4. If so, then use the strategy used at normal mode.
