Currently enjoying your herbal army in your fight against zombies? Then this update will make defending even more difficult.  

The Google Play version of the Plants vs. Zombies 2 just got a recent update that will bring back old foes, and also pack new weapons. 

Dr. Zomboss, the ultimate brain (if he does have one, zombies ate brains you know) of the zombie invasion is coming to another level in Ancient Egypt, which could potentially break what you thought as a fortified tower lineup. 

Fortunately, the update also comes with a new weapon - Snowball Power. Using it, you will be able to freeze all zombies on the screen, giving you more time to take them down one by one. 

This power up is especially important when there are too many zombies to handle for your plants. And with the return of Dr. Zomboss, you will surely need any help you can get to advance to the next time period. 

On its Google Play Store page, the zombie leader would soon arrive to other time periods as well.
