How to unlock the One-Boot Camp achievement in Plants vs. Zombies: Battle for Neighborville - Definitive Guide
If you want to get this as fast as possible, I recommend doing it in Giddy Park, the main hub world. Spawn in as the Foot Soldier (zombies side), and head to the middle area where all the rides are. On the other side from where you came from you should find where the plants come from. Just keep killing them and the cheevo will eventually pop.
