You can spend five dollars in Plants Vs. Zombies 2: It's About Time to advance from Ancient Egypt to the Pirate Seas. You can unlock enhancements with cash, or use your real money to purchase in-game currency, stocking up on power-ups and using them to blow through every level. Or just keep your money and enjoy an experience that's every bit as challenging and rewarding as the original.
