Plants vs. Zombies 4

Plants vs. Zombies 4 is a fan-game of the Plants vs. Zombies franchise developed by Setap GAMES. It was a game based of Plants vs. Zombies 2.

While there was no game called Plants vs. Zombies 3 at the time there was a spin-off game in the chineze market that was considered PvZ3, and that's why it wasn't called Plants vs. Zombies 3.
