Unsodded

Unsodded is a canceled mini-game in Plants vs. Zombies which takes place in day stages and can still be played by using a Cheat Engine.

In this mini-game, there are only three lanes that can be planted on (like in Level 1-2 and 1-3), although zombies will come out in the lanes that cannot be planted. Despite the seemingly difficult appearance of this level, it is actually quite easy because the player is given plenty of time to build their defenses before zombies start coming into the top and bottom rows.

If the player changes the name of a save file from this game to the name of Survival: Endless save files (usually game_13), he or she will get a Survival: Endless variation, which is slightly different from this mini-game: the first and last lanes now appear normal, but they still cannot plant on there, nor will any zombies come from there (they will in the mini-game).

There was a page of Mini-games which were canceled before the release of the game called Limbo Page. The creator did not publish a visible link to this page.

Strategies
Zombies will appear on the lanes where you cannot plant. Therefore, good use of Threepeaters and explosive plants (such as the Cherry Bomb) is recommended. The Starfruit would also come in handy. Gloom-shrooms are also a good choice (they require Fume-shrooms). Do not bring Jalapeno, as it will not affect zombies in lanes that you cannot plant. Avoid plants that can only cover one lane.
