This article is about how to execute the hack on the PC Version of Plants vs. Zombies. For how to do it on the Mac, see I, Zombie hack/Mac.
The I, Zombie hack is a common hack for Plants vs. Zombies which is achieved through editing saved games or Plants vs. Zombies tools. Click here to download Plants vs. Zombies Tools. Unlike most hacks, it does not require Cheat Engine or other external hacking programs. (except Plants vs. Zombies tools) This hack will bring other zombies (like Newspaper Zombie) into I, Zombie Levels.
Note: If you are user two, change "game2_1.dat" instead of "game1_1.dat", or you will change other user's data.
Note: If you change the data and another userdata has the same name, delete the I, Zombie Data that you have.
All the plants you plant in I, Zombie will be changed to Zombies match the table above.
Tricks
Plant as many Zombie Yeti as you can in I, Zombie, then change to Last Stand "game1_31.dat". Use instants to kill all Zombie Yetis and collect the diamonds for easy gold farming.
(GOTY only) Planting the ImitaterTangle Kelp in I, Zombie will not get Zombie Yeti, but get the invisible zombie. Change I, Zombie data with it and kill that zombie with instant kill. You will get the Zen Garden plant. If you did this on the old PC version, it still produces a game crash.
This works well with Unlimited Sun and Instant Refill (see hacking guide).
It is possible to make your own I, Zombie levels like this. First, go to survival: night and make the I, Zombie level setup (sun hack recommended). Then, beat 1 wave. choose the plants that correspond with the zombies you want players to use.
Then, get your sun to what you want it to start at. then, before any zombies appear, change save data from game1_2.dat to game1_61.dat (user 2 is game2_2.dat and game2_61.dat, 3 is game3_2.dat and game3_61.dat, etc.). then, copy/paste the I, Zombie level outside of that folder (keep it #_61.dat). go into I, Zombie, and there you go! If you fail, go to the main menu, delete #_61.dat, and copy/paste the copied file there. To share it, put the file in sendspace, mediafire, etc. and put it up for download.
You can also make your own I, Zombie levels. Firstly, do the same thing on hybrid mini-games and freeze the address. Secondly, play a Night Survival you played. It will show the plants you planted become card-boards. Thirdly, you can play an I, Zombie level without changing user file. (Note: The level still have Lawn Mowers. And you can play it by playing anything, including Zen Garden.)
If you put Tangle Kelp on the leftmost column, and then change it back to survival, you can make the Zombie Yeti eat your brains, provided that there are no lawn mowers on the row where you put the Zombie Yeti at..
