In the IOS and Android versions, the zombies in the trash can in the main interface will increase as the number of players kills, and after killing 10,000 zombies, they will get the title of Undead Space, and the highest part of this zombie pile can also see the entire galaxy.

The charm of Plants vs. Zombies is that some of the levels in the game often appear some, because of the chain reaction between the terrain and the use of plants, resulting in unexpected ways to clear the level, such as in the pirate harbor of Plants vs. Zombies 2, if the holographic nuts are placed on the edge of the map near the sea, the little devil cannon will fall into the sea except for the last shot. If you kill the Fisherman Zombie in the water, The Fisherman 2 Zombie will surface before sinking, and the hand will surface to give a thumbs up, paying homage to the terminator's iconic action.
