What's a good strategy to get the Flower Power achievement?
The key is that speed of zombie spawning is somewhat controlled by how fast you kill them, so try to make it as slow as possible. Potato mines are great early on. Snow peas are also good at doing slow damage. And of course you can just throw up walls for them to slowly eat through. Buy yourself enough time and you should have no problem getting enough sunflowers going.
- try it in Survival Mode.
alternate between the twin sun flower and the Imitater.- stall the zombies with columns of tall nuts and little offense.
