The Xbox Live Arcade, Playstation Network, and DS versions of Plants vs. Zombies have a Vs. mode where each player plays either Plants or Zombies. I'm having a lot of problems when taking the role of the Plants - after the Zombies got a few basic concepts down, the Plants seem to never be able to win. Are there strategies that the Plants can effectively use to win this mode?
Update: In Quick Play mode, gamers cannot customize their seed selections. Plants get Sunflowers, Peashooters, Wallnuts, Potato Mines, Jalapeños, and Squash. The Zombies get Graves, Zombies, Conehead Zobmies, Football Zombies, Garbage Can Zombies, and Wave of Zombies.
