Plants vs Zombies 4

Plants vs Zombies 4 is a tower defense game.

Gameplay
It is like other PvZ titles. However, there is a different system. There will be few plants, but 2 evolution paths for each. Each evolution path can be bought at Crazy Dave’s Shop. You can revert back to the previous evolution. You always start with 100 sun. The "merge" plants can't combine with other merge plants but themselves in order to upgrade them.
