Plants Vs Zombies: Ultimate (formerly known as Integrated or Integrated Ultimate) is a fan-made Plants vs. Zombies mod project that is actively being developed and shared within the community. It's goal is to combine everything from all the different Plants vs Zombies 1 ports (including the Chinese exclusive levels, plants and campaigns), with extra and scrapped content, and even tools to allow community-made levels to be shared, into one complete package.
