Plants´ Randoms: A Full on guide to Highway to the Danger Room: PvZ 2s Modern Day´s Endless Zone (+an update)

So those who are following me on Twitter may have noticed a bunch of pics talking about PvZ 2s Modern Day´s Endless Zone: Highway to the Danger Room, where i talk about how ridiculous it can get. It shows.
An idea popped up to me though: What if i make a guide to it? So here i am, with a Plant´s Randoms post, to explain and guide you all through this madness of a Zone.

The Theme: Highway to the Danger Room takes you through a blast of the past, like Modern Day, with Portals.
Not only we have the *ahem*... Great zombies like Balloon Zombie, Newspaper Zombie and All-Star Zombie, but we also got all types of zombies coming from Portals: Shield Zombies, Weasels and Chickens, Explorers, Bullies. EVERYTHING THAT IS DANGEROUS IS COMING AFTER YOU.
This endless zone becomes insane much later, as zombie waves increase, and Portal spam begins, with Portals even stacking! It get very tedious and hard quickly, but using the correct plants and strategies, you can succeed.


Starting Plants: Moonflower, Dusk Lobber, Nightshade, Shadow-Shroom.
Already you get great plants to begin. Moonflower powers up all the shadow plants, and Dusk Lobber is the strongest Lobbed Plant in the game when powered. Shadow Shroom and Nightshade help against strong zombies.


The Lawn: The most important part to know here are the Portal Spawns. Here are the places they spawn:

Early on, Portals will spawn weak zombies, and also spawn them very far away, but later on, they will spawn way stronger zombies and spawn them closer.
As we can see from the image, columns 1 to 5 will be Portal free, but the rest will be attacked by Portals, which when spawning will move plants away.

Here are the zombies spawned from each portal:
Ancient Egypt: Ra Zombie, Explorer Zombie, Pharaoh Zombie.
Pirate Seas: Seagull Zombie, Pirate Captain Zombie, Barrel Roller Zombie.
Wild West: Piano Zombie, Chicken Wrangler Zombie, Poncho Zombie.
Far Future: Jetpack Zombie, Robo-Cone Zombie, Shield Zombie.
Dark Ages: Knight Zombie, Jester Zombie, Wizard Zombie.
Big Wave Beach: Snorkel Zombie, Surfer Zombie, Octo Zombie.
Frostbite Caves: Blockhead Zombie, Dodo Zombie, Weasel Hoarder.
Lost City: Shovel Zombie, Turquoise Skull Zombie, Bug Zombie (always carries a normal zombie).
Neon Mixtape Tour. 8-bit Conehead and Buckethead, Boombox Zombie.
Jurassic Marsh: Jurassic Imp, Jurassic Fossilhead, Jurassic Bully.

As you can see, we need to deal with all these zombies appearing close to defenses every level. Early on, only weak zombies will appear, like Snorkel, Dodo, etc, but later, stronger ones like Boombox, Octo and Weasel Hoarder will appear. Not only all of this, but you never know what portals will appear each level, making it hard to get plants to deal with the situation.

Not only you get these, but you also need to deal with Modern Day´s own zombies, like Newspaper Zombie, All-Star Zombie, Super Fan Imp, Balloon Zombie and Gargantuars, all of which are either really strong, really fast, or can insta-kill plants.


Strategies: A good strategy is needed to beat all the zombies that might spawn, and with that you also need good plants. Leveled up plants are highly recommended, as the zombie waves are huge.
AOE, or Area of Effect Plants are also recommended, as they can easily deal with the increasing amount of zombies. The aforementioned Dusk Lobber is great, but requires Moonflower to use effectively, and Moonflower is not a great sun producer. Winter Melon, while expensive, can greatly stop, delay and defeat waves of zombies singlehandedly, but will require a better sun producer than Moonflower.

Always, and i mean ALWAYS bring a counter to Jester Zombie, as he can appear anytime during the level, and not having the correct plants means he can just tear apart plants and protect zombies behind him. Snapdragon, or preferably its colder counterpart, Cold Snapdragon, are not only great at stopping Jester, but other zombies thanks to its cooling effect, and can be a cheap and effective alternative to Winter Melon, especially when using Dusk Lobber.

Be sure to use a quick strategy, because Portals can spawn as early as 2 waves of zombies, and they can come in groups of 3-4 each time. Strategies that involve stalling at the beginning are not recommended, because of the quick pace of the Endless Zone.

My strategy is very simple. Simply use Dusk Lobber for damage, and Primal Potato Mine and Cherry Bomb for cleaning. Stunion to Stun threathing zombies like Gargs, All-Stars and Jesters. Primal Wall-Nut to defend, and Power Lily Imitated to supply Plant Food.

When i get Cold Snapdragon however, im replacing Primal Potato Mine for it, as Cold Snapdragon can heavily stall zombies.

So thats pretty much it really. Good Luck!
