PopCap released Plants vs. Zombies on 5 May 2009, and the Game of the Year Edition is the build Steam still sells today. Adventure Mode runs 50 levels across five settings, supported by 49 plants, 26 zombie types and 21 Steam achievements. Dr. Zomboss closes the campaign at level 5 to 10 in his own machine.
This walkthrough takes you from your first session to endgame content. Each phase has specific goals, priorities, and milestones. New to the game? Start with our beginner's guide first.
Quick Progression Summary
| Phase | Area | Focus | Build | Duration |
|---|---|---|---|---|
| 1. Start | Day | Sun economy basics | Straight shooters | 1-2 hours |
| 2. Early | Night | Five lane grid defence mastery | Straight shooters | 3-5 hours |
| 3. Mid | Pool | Seed slots and plant cooldowns + gear | Sun producers or Straight shooters | 5-10 hours |
| 4. Late | Fog | Build optimization | Sun producers | 5-10 hours |
| 5. Endgame | Roof | Min-max | Sun producers or Instant kill plants | Ongoing |
See our maps guide for detailed area breakdowns.
Phase 1: Getting Started (Day)
The front lawn in daylight, where sun falls from the sky for free and the zombie roster stays simple. Level 1 to 10 introduces the Pole Vaulting Zombie, which hops the first plant it meets.
Level/Difficulty: Levels 1 to 1 through 1 to 10 Key Rewards: Peashooter, Sunflower, Cherry Bomb, Wall-nut, Potato Mine, Snow Pea, Chomper, Repeater
What to Do in Day
- Learn Sun economy. Every plant costs sun, each falling sun is worth 25, and a Sunflower at 50 sun pays for itself in under a minute. Spend your first session getting comfortable with this.
- Pick Straight shooters as your starting build. See our builds guide for why.
- Plant the first two columns entirely with Sunflowers before you plant a single shooter. Sun is the only currency in the game, and a lawn that reaches roughly eight producers by wave three can afford Melon-pults later while a rushed defence never can.
- Acquire your first equipment upgrade: Sunflower or whatever's available.
- Clear all main content before moving on.
Phase 1 Checklist
- Understand Sun economy fundamentals
- Straight shooters selected and functional
- Day main content cleared
- Ready for Night
Phase 2: Early Game (Night)
The same lawn after dark, with no free sun and gravestones blocking tiles. Mushrooms are cheap or free to compensate, and Grave Buster removes the stones before they release anything.
Level/Difficulty: Levels 2 to 1 through 2 to 10 Key Rewards: Puff-shroom, Sun-shroom, Fume-shroom, Grave Buster, Hypno-shroom, Scaredy-shroom, Ice-shroom, Doom-shroom
What to Do in Night
- Work on Five lane grid defence. Zombies walk right to left along five fixed lanes, so a lane is either defended or it is not. This system becomes critical from here on.
- Farm for Sunflower if you haven't already. It's the key upgrade for this phase.
- Use Potato Mine as your opening defence rather than Peashooter. At 25 sun it kills the first zombie outright, and the sun you save goes straight into another Sunflower, which compounds for the rest of the level.
- Complete all objectives before pushing to Pool.
- Consider whether Sun producers might suit your playstyle better than Straight shooters.
Phase 2 Checklist
- Five lane grid defence integrated into gameplay
- Sunflower acquired
- Night fully cleared
- Ready for Pool
Phase 3: Mid Game (Pool)
The backyard in daylight, with two water lanes cutting through the middle of the six row grid. Every plant in the water needs a Lily Pad underneath it, and Dolphin Rider Zombies leap over your first defender.
Level/Difficulty: Levels 3 to 1 through 3 to 10 Key Rewards: Lily Pad, Squash, Threepeater, Tangle Kelp, Jalapeno, Spikeweed, Torchwood, Tall-nut
What to Do in Pool
- Master Seed slots and plant cooldowns. You start with six seed slots and buy more from Crazy Dave, and every plant has its own recharge timer. This unlocks a new layer of gameplay.
- Start working toward Peashooter. It's the best equipment and becomes accessible around now.
- Check the Almanac before a level with an unfamiliar zombie. It tells you flatly that a Screen Door Zombie blocks peas with its door but takes full damage from lobbed plants, which is information that saves an entire attempt.
- This area is the main skill check. If you can clear it, you're ready for late game.
- Start investing in Setting specific rules per area for the tactical depth you'll need going forward.
Phase 3 Checklist
- Seed slots and plant cooldowns mastered
- Peashooter acquired or in progress
- Pool fully cleared
- Ready for Fog
Phase 4: Late Game (Fog)
The pool at night, with heavy fog hiding the right half of the lawn so you cannot see what is coming. Plantern at 25 sun clears a circle of it, and Blover blows the fog away briefly along with Balloon Zombies.
Level/Difficulty: Levels 4 to 1 through 4 to 10 Key Rewards: Sea-shroom, Plantern, Cactus, Blover, Split Pea, Starfruit, Pumpkin, Magnet-shroom
What to Do in Fog
- Finalize your build. You should be running Sun producers or Straight shooters with optimized gear.
- Peashooter should be your primary. If you don't have it yet, prioritize getting it.
- On night levels lead with Puff-shroom, which costs zero sun. A full front column of them holds the opening waves for free while your Sun-shrooms mature from 25 sun sprouts into full producers.
- Almanac and Crazy Dave's shop optimization starts here. Small improvements compound into massive advantages.
- Farm this area for the resources needed to push into Roof.
Phase 4 Checklist
- Build fully optimized
- Peashooter upgraded to max
- Fog fully cleared
- Ready for Roof
Phase 5: Endgame (Roof)
A sloped rooftop where nothing can be planted without a Flower Pot and straight shooters fly over anything standing close. Bungee Zombies drop in to steal plants, and the campaign ends here against Dr. Zomboss.
Level/Difficulty: Levels 5 to 1 through 5 to 10 Key Rewards: Cabbage-pult, Flower Pot, Kernel-pult, Coffee Bean, Garlic, Umbrella Leaf, Marigold, Melon-pult
What to Do in Roof
- Roof tests everything. Come prepared with your best build and gear.
- Bring a Plantern to fog levels every time. Without it the right half of the lawn is invisible and you will only notice a Buckethead when it is already eating column two.
- The endgame loop: run Roof, optimize gear, push harder content.
- Experiment with Instant kill plants for a fresh take once you've mastered the standard builds.
- This is where Almanac and Crazy Dave's shop mastery separates good players from great ones. See our tips guide for advanced strategies.
Phase 5 Checklist
- Endgame content on farm
- Best-in-slot gear acquired
- Roof fully cleared
- Ready for challenge content
Common Progression Mistakes
- Planting shooters before Sunflowers. A lawn that skips its economy holds the first three waves comfortably and then collapses because it can never afford a Melon-pult at 300 sun.
- Spending Cherry Bomb on a single zombie. Its recharge is one of the slowest in the game, so a wasted one leaves you without an answer when a real cluster arrives.
- Using straight shooters on the roof. The slope makes peas fly over close zombies entirely, which is why every roof level hands you catapult plants instead.
- Ignoring the Zen Garden. Watered plants pay coins over time, and coins buy the seed slots and upgrade plants that Survival Endless requires.
- Forgetting Lily Pads in the pool. Water tiles reject every land plant, and a defence that only covers four of the six lanes loses to the first Dolphin Rider that arrives.
Key Tips for Smooth Progression
- Plant the first two columns entirely with Sunflowers before you plant a single shooter. Sun is the only currency in the game, and a lawn that reaches roughly eight producers by wave three can afford Melon-pults later while a rushed defence never can.
- Use Potato Mine as your opening defence rather than Peashooter. At 25 sun it kills the first zombie outright, and the sun you save goes straight into another Sunflower, which compounds for the rest of the level.
- Check the Almanac before a level with an unfamiliar zombie. It tells you flatly that a Screen Door Zombie blocks peas with its door but takes full damage from lobbed plants, which is information that saves an entire attempt.
- On night levels lead with Puff-shroom, which costs zero sun. A full front column of them holds the opening waves for free while your Sun-shrooms mature from 25 sun sprouts into full producers.
- Bring a Plantern to fog levels every time. Without it the right half of the lawn is invisible and you will only notice a Buckethead when it is already eating column two.
