We knew that Plants Vs. Zombies 2: It's About Time was in development, and now developer PopCap has announced it will be released on July 18th for iOS. In this sequel, time-traveling has been added so you'll be gardening against zombies in the past and future.
Screenshots show the basics of the game to be pretty unchanged. Novelty will come with new zombies to fight, and new plants to fight them with. There will also be new power-ups from Crazy Dave, who will join you as you battle in various themed worlds.
One way Plants Vs. Zombies 2: It's About Time will be different is that it's free to play. This means there will be optional in-game purchases, though PopCap stress you can play everything the game has to offer without playing. It will be interesting to see how the excellently balanced gameplay of the original will be affected by the free to play model, which has been pretty damaging to some games like Real Racing 3.
If you never played the original Plants Vs. Zombies, what are you waiting for?
