PvZ: Armageddon

"It's coming"- The game's tagline

PvZ: Armageddon is the third game in the Plants vs. Zombies series.

Story
Insane zombie genius and former inventor Dr. Edgar Zomboss, has created a portal, escaped to a supposedly uninhabited planet and now is preparing to launch the missiles needed for a nuclear armageddon at Earth, but the primitive Plants who inhabited the planet, called on the help of you, the owner, to stop Zomboss from taking over their planet and destroying Earth.

Gameplay
PvZ: Armageddon is quite similar to the other PvZ games, but has some major differences. The first is that upgrades return, but in 5 tiers. These are Basic, Upgrade, Master, XL and Ultimate. Basic, is self explanatory and the normally unlocked plant. Upgrade is the second tier, which are stronger and more reliable, Master is the third, with plants strong and durable, often with high attack power and health. XL, or Full Potential, has super powered plants, who are very strong and often depicted as plants with multiple abilities and made of energy. Finally, Ultimate Plants- Physical once again, but powered with armour and weapons, containing true power. The second difference is that a new type of creature- Plantive is introduced. They are on your side and an become different by evolving in Timestop Devices. Finally, the main difference is that, instead of the normal 'Defend your Brains' thing, this game has much different ones, such as destroying a missile, breaking a cage, etc.
