The group will face a new zombie threat as a new breed of zombie has developed. This new super-zombie type is faster, bigger, and stronger than the previous strain of zombies and harder to kill. These super-zombies have started grouping up into a horde going from city to city leaving a path of destruction behind them.
"Tallahassee, the senior zombie-killer played by Woody Harrelson in “Zombieland: Double Tap,” has a catchphrase that’s a little too naughty for me to quote. You’ve probably heard it before, and you might agree with another character’s assessment: “That saying is very 2009."
"At a relatively brief 99 minutes, Zombieland: Double Tap doesn’t provide one with anywhere near enough time to figure out exactly why Zombieland: Double Tap exists. The closest I could manage was sheer greed, but even that explanation would require a strongly held belief that a substantial fanbase cared about or even remembered the original."
