First, you need these.
- Instant recharge. (Press F3)
- Unlimited Sun (Press F1)
- First Aid Kit (For wallnuts, tallnuts, pumpkins)
WHAT TO DO:
1. From the top, place Tall Nuts 1 space away from where the zombies come from.
2. Place another below that row, 2 spaces away from where the zombies come from.
3. Place another below that row, 3 spaces away from where the zombies come from.
4. Keep following that pattern down the row. Of course you can place all tall nuts in one row, but then but them 1 space away from where the zombies come from.
5. Leave one row open. (any row is fine.)
6. Place Magnet Shrooms in the row you left open.
7. Place Marigolds in the remaining place.
8. As the zombies come, to protect your other plants blow them up using Cherry Bombs. (You can use Doom Shrooms - But not recommended. You can also use Jalopenos.)
9. Wait, and let the zombies stay there. When the Tall-nuts get weak, place tall nuts over them.
You can use F2 to use unlimited money, but this way is a lot more fun!
(To use: F1, F2, F3, you need the PvZ trainer. Google it then download it, and run it.)
