Gameplay
Plants vs. Zombies 2: It's About Time is a free-to-play game, unlike its predecessor. Plants vs. Zombies 2 supports in-app purchasing of coins in order to utilize certain power ups abilities. However, it is theoretically possible to complete the whole game without purchasing these abilities. Players can optionally start with a tutorial on the basics of the game. This takes place in the player's house. After the tutorial, or immediately if the player chose to skip it, the player time-travels first to Ancient Egypt and then to the Pirate Seas and Wild West. A future level, hinted at in-game, is titled the "Far Future".
Plot
The player receives a bottle of hot sauce which Crazy Dave, the player character's neighbour, eats with a taco. Crazy Dave is determined to eat exactly the same taco again, so he uses a sentient time machine in the form of an RV, named Penny, to travel back in time to have the taco again. Due to a malfunction, he ends up stranded in Ancient Egypt. The player must then defeat zombies there, followed by the Pirate Seas and subsequently the Wild West. After defeating the Wild West, Crazy Dave and Penny notice a new world called the Far Future.
