Adventure Mode

Peashooter Introduction Peashooter shoots pea for one lane. It costs 100 suns.

Guide: 1-1
The first level is simple in this level you have only 2 seed slots and only have 2 plants. It has a tutorial in-game. Please follow the arrows. And use as much peashooters as you can. You only have 1 lane. These are the sections of the level:

'''Standard Wave - 5 Zombies Final Wave - 2 Zombies '''

Random: Place any plant anywhere. Strategy: Place plant at the back so no zombie can get there.

After defeated level, you get sunflower.

Sunflower Intro This plant is useful for getting sun, mostly for 2-1 to 2-10 and 4-1 to 4-10. It costs 50 suns.

Guide: 1-2
Second level is really easy. It has 3 lanes. Each one always spawns randomly so the number of zombies is not the same. Plant 3 sunflowers at the back. And get at least or every time there is a zombie, get 300 suns for 3 peashooters at the front and then, 3 more peashooters at the next 2 lanes. Stare at the screen for the zombies' failure. Always put sunflowers at the back.

Cherry Bomb Intro
This plant explodes upon planting it. It costs 150 suns.

Guide: 1-3
Third level has 5 lanes. It has more zombies than 1-1 and 1-2 combined (Depending on how many zombies in 1-2). Rather here they have a new type of zombie and you get a new plant, Wall-nut. Always put sunflowers at the back.

Wallnut Intro
He protects your plant for a few minutes and then, gets fully swallowed by a zombie. Useful for very strong zombies, like bucket head, cone head, etc. Guide: 1-4 This is kind has a tiny little challenge. They have their toughness at high. At least Pop Cap was nice enough to give cherry bomb before this. Always put sunflowers at the back.

Shovel Intro
Let's you dig up a plant and lets you make room for another plant.

Guide: 1-5
This is the first time you meet your neighbor, Crazy Dave! He talks to you about himself and gives you a wallnut. He asks "Why do I have a wallnut in your hand?" and he replies and finally after hearing Crazy Dave's stupid conversation. You will first unplanted peashooters then, you bowl zombies. Yes, you BOWL zombies using wall-nuts. It gives you a lot of money. But after that craziness you get, Potato Mine!

Potato Mine Intro
This is the 2nd exploding plant you get. But, this takes 30 seconds to arm it. It only explodes upon contact. And the explosion is very short-ranged.

Guide: 1-6
This is where the fun begins. You get a lot and I mean a lot of zombies. Yes, of course you always get a lot of zombies on the next levels. So, get ready to soil your plants! After defeated, an exceptionally helpful, but expensive plant gets in your hands! It's Snow Pea!

Snow Pea Intro
Snow Pea launches peas that deal damage and slows down the zombie at the same time! Wow!

Guide: 1-7
Well, of course, still a big amount of zombies for starters. And you get another plant, Chomper.

Chomper Intro
Well, despite that you can tell what he does by his name, he devours the zombie whole!

Guide: 1-8
This half-way through of Part 1 of this guide. This place is has a ton of zombies for starters. Another plant, I think. Yes, there is, Repeater.

Reapeter Intro
RePEAter Yes, Pop Cap intended to make fun of at least one plant and that was her. Repeater is the helpful companion of Peashooter. It shoots 2x in a row.

Guide: 1-9
This is towards the end of front yard (Day). No new plant here. This is just challenging for (still) beginners.

Guide: 1-10
Finally! The game configuration is finally changed! The conveyer belt pops up at every 10 levels of the game. And it also marks the end of a place at your home. At 1-9, the end of it is they give you a note saying:

?????, We are going to launch an all-outing attack to your house. Sincerely, Zombies They throw different zombies at you while you get random plants from the conveyer belt which is free. It thinks a new plant!

Puff-shroom
Puffshroom Intro Don't worry, I won't say anything, Crazy Dave will explain. And they're free!

Front yard (Night) Guide: 2-1
You can't get falling sun at night. You depend on sunflower for sun. Puff-shrooms are the key here, because of lack of sun. So use puff-shroom for defending your home. Again, a new plant! Sun-shroom?!

Sunshroom
Sun-shroom Intro I found a few questions regarding this plant. One of the very specific is "How does a plant that hates sun, make sun?” Yes, I know, don't question gaming logic. It gives 15 suns for the first 2 minutes and then, it give 25 suns (normal).
